The MULTIGRADE 600 enlarger head and control system is for use on professional enlargers where negative coverage is required up to 12.7x10.2cm (5x4 inches). The system incorporates advanced electronics, and offers the black and white printer finger tip control of a wide range of contrasts. a b c d 1.1 a b The MULTIGRADE 600 system comprises the following elements: MULTIGRADE 600H enlarger head MULTIGRADE 600C control unit MULTIGRADE 600S power supply MULTIGRADE 600P contrast and exposure probe OPTIONAL EXTRAS Available as optional extras are: A range of light mixing boxes from 35mm up to 5x4inches. MULTIGRADE 600F footswitch 5 2 DESCRIPTION The MULTIGRADE 600 system is easy to install and straightforward to use. By following the instructions in this manual, quality prints, together with continuous and reliable operation, are assured. 2.1 MULTIGRADE 600H ENLARGER HEAD See figure 2.1. MULTIGRADE 600H Figure 2.1 MULTIGRADE 600H enlarger head The MULTIGRADE 600H diffuser enlarger head replaces the original condenser, diffuser or cold cathode lamphouse used with a range of professional enlargers. It is fitted to the enlarger chassis using an adaptor kit, designed to make installation quick and relatively simple. 2.1a Light source The enlarger head is fitted with a fan cooled high output halogen lamp, heat filter and motorized yellow and magenta dichroic colour filters. The lamp is kept running at low power (pre-warmed) whenever the system is switched on, to provide quick start-up and consistent results. The cooling fan runs only while an exposure is being made. Extremely stable and repeatable exposures are provided by a proven closed loop light monitoring system and motorised light shutter mounted in the base of the head, just above the light mixing box. Light from the filters is reflected and diffused in the mixing box to provide even illumination of the negative. The colour variation obtainable enables the wide contrast range, available with ILFORD variable contrast papers, to be used to its full advantage. 6 Note A single servo motor drives both filter carriers. At one extreme, the magenta filter is fully in the light beam (Grade 5). At midtravel, both filters are clear of the light beam and white light is transmitted (at Grade 2.5) giving maximum printing speed. At the other extreme, the yellow filter is fully in the light beam (Grade 00). The yellow and magenta filters can never both be in the light beam at the same time. 2.1b Light mixing boxes A range of light mixing boxes is available, including sizes 35mm, 6x6cm, 6x7cm, 6x9cm and 5x4inches. The box or boxes required are not included with the MG600 system and must be ordered separately. Additional boxes may be ordered at any time to suit user requirements. To fit the light mixing box, see section 4.1a. 2.2 MULTIGRADE 600C CONTROL UNIT See figure 2.2. ILFORD MULTIGRADE 600C PAPER/MEMORY CALIBRATION GRADE TABLE TIME/PRINTS 8 8 8 8_ 8 8 8 + PAPER NEW ADJ.

CONTRAST YELLOW MAGENTA DENSITY GRADE CALIBRATION MEMORY GRADE % TIME BURN FOCUS EXPOSE GRADE TABLE CLEAR PRINT COUNT Figure 2.2 MULTIGRADE 600C control unit The MULTIGRADE 600C control unit is quick and simple to operate. Once the exposure time and contrast are established, the permanent microprocessor controlled closed loop system checks light intensity and colour before each exposure. A correction is made automatically to the exposure time and filtration (if required) to ensure consistent print results time after time. 7 The control unit provides five paper channels. Four are preprogrammed for ILFORD papers (see section 2.7) and one is left free for programming by the user, if required. Note All channels can be checked and/or re-programmed (see section 8). The control unit also incorporates calibration facilities to ensure that the desired print density and grade are obtained when scanning an image with the probe (see section 8 ). All controls are described in section 3. For maximum operator safety, the control unit is powered entirely by low voltages supplied from a remote power supply (see section 2.3). The brightness of the display and button indicator lights optimised to be seen under normal darkroom lighting. During normal use, the displays will not fog ILFORD variable contrast papers or other black and white paper of similar sensitivity. 2.3 MULTIGRADE 600S POWER SUPPLY See figure 2.3. MULTIGRADE 600S ILFORD HEAD ROLL-PAPER FOOTSITCH KEYBOARD POWER 0 I F1 Figure 2.3 F1 MULTIGRADE 600S power supply unit The MULTIGRADE 600S stabilised power supply is connected directly to the electrical mains supply. It has sockets for connecting the enlarger head, control unit and footswitch or roll easel, positioned on the rear of the unit. The on/off switch, showing ‘O’ in the off position, controls power to the system. 8 CAUTION The unit is factory set to mains voltage of 230V. Before switching on the unit please check the correct mains voltage is selected and the correct fuse is fitted, see section 4.2a. 2.4 MULTIGRADE 600P EXPOSURE PROBE See figure 2.4. Figure 2.4 MULTIGRADE 600P exposure probe The MULTIGRADE 600P probe saves paper and time by eliminating the need to make test strips or sheets. The brightest and darkest parts of the image are scanned and the readings obtained enable exposure time and grade to be automatically calculated and displayed. For a detailed description of how to use the probe, see section 7. 2.5 MULTIGRADE 600F FOOTSWITCH The MULTIGRADE 600F footswitch is available as an optional extra, and enables the printer to keep both hands free. The function of the footswitch is to start an exposure only. If an exposure in progress is required to be cancelled, this must be done on the control unit. 9 2.6 AUTOMATIC ROLL EASEL The MULTIGRADE 600 system can be connected to most automatic roll easels. Connection is made via an 8-pin Siemens plug (as typically used on Durst roll easels). Please contact ILFORD for inter-connection details. 2.7 PHOTOGRAPHIC PAPERS The MULTIGRADE 600 system is designed for use with ILFORD MULTIGRADE variable contrast papers. 2.7a MULTIGRADE paper The control unit is pre-programmed for the following papers: P1 ILFORD MULTIGRADE IV RC Deluxe P2 ILFORD MULTIGRADE RC Warmtone P3 ILFORD MULTIGRADE IV FB Fiber P4 ILFORD MULTIGRADE FB Warmtone P5 Spare channel 2.7b Other papers Colour prints or prints from graded papers such as ILFORD ILFOSPEED can be made using an appropriate setting from one of the paper channels (grade 2.5) where both yellow and magenta filtration values are set to zero, ie the enlarger head is projecting white light. See section 12. Alternatively, if it has not been reprogrammed, any grade setting in paper channel 5 (P5) may be used. During use, the control unit will display the grade set but this will have no relevance to the prints being made. 10 3 CONTROLS See figure 3.1.

The buttons control grade selection from 5 (highest grade) to 0.0 (low grade) in 1/10 grade steps. At setting 0.0, a further press of the – button selects the lowest grade 00. Holding the +/– buttons down causes the display to roll sequentially in increments of 1/10 grade. Note When making changes to the grade setting, any necessary changes to the exposure time to maintain a constant print density will be automatically set by the control unit. 3.2 PAPER/MEMORY GRADE TIME/PRINTS 14.5 ON L.

Time is displayed in hundredths of a second for 1.00 to 9.99 seconds, tenths of seconds for 10.0 to 99.9 seconds and in whole seconds from 100 to 999 seconds. The display counts down to zero during main exposures, then resets to the set value. The required exposure time is set using the +/– buttons. A short press will increment the set value. Keeping a button depressed will cause the time to roll up or down. The roll rate increases if the button is held depressed for more than two seconds. 11 Note The exposure time cannot be incremented in less than 2% steps. Exposure time may also be adjusted using the ‘% Time’ button. When the ‘% Time’ button is depressed, the time display shows zero. Whilst holding this button depressed, the required percentage time adjustment can be set using the +/– buttons. On release of the ‘% Time’ button, the corrected time is displayed. The operating range of % Time is –99% to +999%. Note When an exposure is initiated, the closed loop control system assesses colour and brightness of the exposing light before the shutter is opened to begin the exposure. Any necessary corrections to maintain a constant exposure are made automatically and this could result in the set exposure time changing to a different value, from which the countdown then begins. This is normal operation for the system. The effect will become more pronounced (an increase in exposure time) as the lamp ages and its light output reduces, or the colour filters become dirty, etc. LIBRATION GRADE 3.3 EXPOSE With the time and grade selected, start the main exposure by pressing the ‘expose’ button. The time will count down to zero. Exposure can be stopped at any time by pressing the ‘expose’ button. Pressing the expose button again will re-start and complete the remaining exposure. If the remaining exposure is not required, pressing the ‘clear’ button resets the timer to the original exposure time. 3.4 FOCUS To obtain a continuous light suitable for focusing and composition, press the ‘Focus’ button. To cancel the ‘Focus’ mode, press the ‘Focus’ button again (or the ‘Clear’ or ‘Expose’ buttons). 3.5 PRINTS COUNTER The control unit automatically counts the number of main exposures (additional burn-in exposures are not counted). This is particularly useful if a run of identical prints is made from one negative. To obtain the display, simultaneously press the ‘Focus’ and ‘Burn’ buttons.

CAUTION Installation of the MULTIGRADE 600 system is very straightforward. However, if you are in any doubt about making any of the electrical connections, consult a competent electrician. Ensure the mains electrical supply is switched off before connecting or disconnecting any plug. 4.1 ENLARGER HEAD For information on fitting the enlarger head to your particular enlarger, refer to the separate leaflet supplied with the adaptor kit. During installation, remove the top access cover (see section 9) and remove the transport securing device (screw and bush). Replace the top cover. Connect the head to the appropriate socket on the power supply. 4.1a Changing light mixing boxes See figure 4.1. MULTIGRADE 600H MULTIGRADE 600H Figure 4.1 Changing light mixing boxes To minimise exposure times, a light mixing box should be fitted which suits the negative format being printed. 1 To fit a light mixing box: With the negative carrier removed, move the two slide catches, which retain the mixing box, to the forward position. 15 MULTIGRADE 600H MULTIGRADE 600P MULTIGRADE 600C MULTIGRADE 600S MULTIGRADE 600F Figure 4.2 Installation 16 2 Ensure the mixing box format/size label is facing the front (eg 24x36mm). 3 Locate the mixing box in position and lift upward to locate the retaining pins into their slots. 4 Move both slide catches backward to lock the mixing box in position. 5 Refit the negative carrier. Removal of the mixing box is the reverse of the above procedure. Support the mixing box to prevent it from dropping downwards as the slide catches are released. 4.2 4.2a POWER SUPPLY Supply voltage WARNING The power supply is supplied with the voltage selector set to 230V and a 2.5A fuse fitted. Before switching on, check that this is correct for your electrical mains supply. If it is not, carry out the following procedure. Remove the bayonet fitting fuseholder cap, complete with fuse (F1). 2 A two position supply voltage selector is located on the rear panel enabling the appropriate input voltage to be selected in accordance with the electrical mains supply. 230V 1 F1 230V T2.5A 115V T5A F2 T 12.5A a b Position the 2-position voltage selector to the correct setting. For supplies 110-120V, 50/60Hz, set to the 115V position. For supplies 220-240V, 50/60Hz, set to the 230V position. 3 a b Fit the correct fuse, supplied with the unit (see section 11). For 115V insert T-5.0A fuse. For 230V insert T-2.5A fuse. 17 4.2b Working environment The power supply is totally enclosed and becomes warm with extended use. It is advisable to position the unit so that adequate all round ventilation is provided at all times. CAUTION For safety reasons, do not position the power supply on the floor. When the power supply had been positioned, ensure there is enough slack in the lead to the enlarger head, to allow full travel of the head on the enlarger column. 4.2c a b c Connection to mains supply If a moulded plug is not fitted to the mains cable provided, connect a plug of at least 10A rating as follows: Brown wire to the live pin (marked L ). Blue wire to the neutral pin (marked N ). Green/yellow wire to the earth pin (marked E or ). Connect the other end of the mains cable to the ‘power input’ socket on the power supply. Ensure the plug is pushed fully into the socket. 4.3 ENLARGER HEAD Connect the enlarger head to the appropriate socket on the power supply. 4.4 CONTROL UNIT Connect the control unit lead to the appropriate socket on the power supply, and tighten the two retaining screws. 4.5 FOOTSWITCH Connect the footswitch to the appropriate socket on the power supply. 4.6 EXPOSURE PROBE Connect the probe to the appropriate socket on the control unit, and tighten the two retaining screws. 18 5 PRINT MAKING STANDARD METHOD 1 Switch the system on. Note The control unit will display the values set when it was last switched off. Select the required paper channel for the paper type you are using. 2 Locate your negative in the enlarger. Select ‘Focus’ to project white light for focusing, composition and assessment of the image. When satisfied press ‘Focus’ again to cancel. 3 Select the contrast required. See section 3.1. 4 Select the estimated exposure time. See section 3.2. 5 Position a sheet of ILFORD MULTIGRADE paper on the enlarger base board. Expose the sheet by pressing ‘expose’. 6 Process the exposed paper. Check the print for density. If necessary, correct the exposure and make another print. 7 Check the print for contrast. If necessary, make another print at a different grade. It is not necessary to alter the exposure time when changing grades. This is done automatically by the control unit to ensure that a constant mid-tone density is maintained. In this example, exposure time had automatically changed from 13.0 to 16.3. 19 6 PROGRAMMING THE MEMORY PAPER/MEMORY GRADE TIME/PRINTS 1 The values shown in the following diagrams are given for example only. Set the paper channel main exposure time and grade required in the normal way. 2 Press ‘memory’. ‘1E’ will appear in the memory display indicating that the control unit is now in memory mode. The exposure time and grade set above have now become the main exposure 1E, to be followed by burn-in exposures 2E, 3E and 4E. 3 Press ‘memory’ again and ‘2E’ will appear in the memory display. As a start point, this second exposure always sets to 50% of the main exposure (at the grade setting previously left in the memory). 4 Reset the exposure time and grade to the settings required for the second exposure (first burn-in memory). 5 Press ‘memory’ again to select the third exposure. The last grade value used will appear in the display. An exposure time may appear if it was not previously cleared. 6 Set the exposure time and grade to the settings required for the third exposure. 7 Repeat 5 and 6 to set the fourth exposure if required. If not required, cancel the exposure time by pressing ‘Clear’.

If only the main exposure is required, set the control unit back to normal mode with a paper channel showing in the display. c If the main exposure time is reset (when either set to a paper channel or to ‘1E’) then the times set in all memories will be reset in the same ratio. The grade settings are unaffected. If any recalculated exposure time is less than 1.0 seconds, the value will be displayed but will flash indicating that this exposure cannot be made. d Pressing ‘ % Time’ when the display is showing memories 2E, 3E or 4E indicates the burn-in exposure as a percentage of the main exposure 1E. 21 7 PRINT MAKING USING THE PROBE See figure 7.1. Figure 7.1 1 Using the MG600 exposure probe Insert the negative to be printed into the enlarger. Select ‘Focus’. Focus and compose the required image and set the working aperture (f-stop) of the lens. Select the appropriate paper channel on the control unit. 2 Check the probe LED is switched on. Position the probe photocell in the brightest area of the projected image and press and hold the probe button. Note The probe button must be held down during the complete measurement cycle. 3 When the probe LED extinguishes move the probe measuring cell over the brightest and darkest areas of the image. Release the probe button. 4 The calculated exposure time and grade is then displayed. Unless you wish to make a further measurement, cancel the focus light and prepare to make a print. 5 Position a sheet of paper on the enlarger baseboard. Press ‘expose’. The sheet is given the calculated exposure. Process and assess the final print. 6 The exposure probe can be used if the control unit has stored memories. Note The exposure times set in the burn-in memories will be modified in the same ratio as the new and previous main exposure times. The grades set in the memories are unaffected (see section 6 Note c). 22 7.1 PAPER/MEMORY GRADE TIME/PRINTS 1 Pressing the probe button opens a shutter covering the measuring cell and begins the measuring cycle. 2 During scanning, the probe takes ten readings per second. The highest and lowest readings are stored and enable the grade and exposure time to be calculated. 3 Also during scanning, the display shows the previously set grade and a number which represents the density being measured by the probe. This enables the lightest and darkest areas of the image to be found (if necessary). The difference between the highest and lowest numbers represents the contrast of the negative. 4 If the light level measured is too low, the display will show Pr bd HI (Probe density high). The lens aperture should be increased and a new probe measurement taken. P1 2.5 195 PAPER/MEMORY GRADE P PAPER/MEMORY P TIME/PRINTS HI GRADE USING THE EXPOSURE-CONTRAST PROBE SOME NOTES AND GUIDELINES If used correctly, the MULTIGRADE 600P exposure probe can be of great benefit to the black and white printer. Listed below are some simple rules to observe in order to maximise the probe accuracy. TIME/PRINTS If the light level is too high, the display will show Pr bd LO (Probe density low). The lens aperture should be reduced and a new probe measurement taken. LO 5 The probe is not affected by normal levels of darkroom safelighting. However a very bright safelight situated close to and above the enlarger baseboard could have an effect. This can easily be checked. Operate the probe button to initiate a probe measurement. View the density value being displayed on the control unit (see 7.1 para 3 above) and switch the local safelight on and off. If the number displayed is affected, then for accurate results, this safelight should be re-sited or switched off when using the probe. 6 If the paper channel is changed, the image must be measured again for accurate results. 7 Obtaining good results with the probe requires some familiarisation with its use. It is not necessarily the absolute brightest and darkest parts of the image which should be scanned, but rather the areas in which detail still needs to be seen in the resulting print. Extreme dark areas or highlights should therefore be avoided when scanning. 8 The MULTIGRADE 600 system is programmed to calculate the correct exposure time for a wide range of negatives. Inevitably, there will be some negatives (showing extremes of exposure or development or not having a suitable area from which to take readings) that may produce inaccurate results. If continued difficulty is found in obtaining a high percentage of correctly exposed prints, the probe may be re-calibrated (see section 8). 23 8 PROGRAM STRUCTURE 8.1 Paper Channels BASIC CALIBRATION AND DATA ENTRY The program consists of five paper channels, each with the following structure: Probe Calibration Channel 1 Density calibration - ‘New Cal’ Channel 2 Calibration adjustment - ‘Cal Adj’ Channel 3 Contrast adjustment - ‘Contrast Adj’ Channel 4 Grade Table Channel 5 Paper grade table - ‘Grade Table’ Grade 00 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 8.2 8.2a Contrast Yellow Magenta D-Comp See tables in section 12 CALIBRATION OF THE EXPOSURE-CONTRAST PROBE The ‘Calibration’ function allows the basic setting up of the system to obtain the correct exposure times (density) and grade, when using the probe. Density calibration - ‘New Cal’ and ‘Cal Adj’ The density calibration factor ‘Cal’ is displayed on the control unit in ‘Cal Adj’ mode. the value of ‘Cal’ is determined by making test prints and is directly linked to exposure time determined by the probe (it represents paper speed). ‘New Cal’ should be used to calibrate the probe for new batches of paper. ‘Cal Adj’ is best used to reset the calibration to predetermined values. For example, to reset to values determined under ’New Cal’ and then written on the paper box for reference. Fine tuning can also be carried out by small adjustments of the ‘New Cal’ value to compensate for a drift in processing chemistry activity, for example. 24 Density calibration is only possible by using the following procedure, during which a probe measurement must be made when the control unit displays ‘Measure’. To calibrate proceed as follows: Select an average production negative of good tonal range which you would expect to be printed at grade 2.5 and place in the enlarger. Press ‘Focus’, adjust and focus an image of approximately 20x25cm (8x10in) onto the baseboard. Set the working aperture on the lens.

Note Changing the value in ‘Cal Adj’ only changes the exposure times determined by the probe. 25 8.2b Grade calibration - ‘Contrast Adj’ This function allows the grade (contrast) value determined by the probe to be offset by ± 30% (an adjustment of approximately ±1.5 grades). It also enables personal taste to be taken into account and can provide matching between two batches of paper. A change to ‘Contrast Adj’ results in a print contrast being obtained which is either higher or lower than the value determined by the grade table. The grade correction function only fully affects the grade values (as determined by the probe) in the range 1.0 to 4.0. The available offset from 1.0 towards 00 and from 4.0 towards 5.0, reduces as the extremes of the range are approached. PAPER/MEMORY GRADE TIME/PRINTS P1 CALIBRATION NEW CAL.
