Using a color enlarger to print both color and black and white photos

Some enlargers have dials on the front that are labeled yellow, cyan and magenta. These enlargers are made to print both black and white and color photos. To print in colors you use the dials to perfect the colors of your print. Let say that you took a picture and the colors look to be a bit off. In the light you would hold up a color filter to the image and decide which filter makes the color look closest to what you want the final image to look like. Then taking the information on the card you go back into the dark room and adjust the dials on the enlarger according to the card that was used. If you were looking through a green filter then you would lower the number on the magenta dial.

Printing in black and white on an enlarger with these dials is a little different. Since there are no colors in the black and white paper these dials have a different function. They are used to adjust the contrast of an image. If you turn the light on in the enlarger without paper under it and turn the dials you will notice that the magenta will make the light darker. When you print with the yellow and cyan dials at 0 and magenta at around 10-20 this will add contrast the image. You can always develop all your negatives without touching any of these dials, but if you can master them then your images will have a little less flat than those with little to no contrast.

if black ink is out, will copy in color possible from pc? Also how do I reset this printer?


Dear
Since the model is not found, its difficult to say. however in most cases the subtractive colors are used ie cyan,magenta and yellow. with mixing these white is produced but in case of basic color used ie. red,green and yellow, on mixing these black color is produced. Mostly cyan, magenta and yellow is used hence you can not produce black color so the a complete color print not possible.
Thanks.

Does black and white photography use the same enlarger as color photography?


Black and white photography uses a much more basic enlarger, you will notice that some enlargers have knobs on the front that are magenta, cyan and yellow these are color enlargers. A color enlarger can be used to develop black and white images but a color image cannot be developed using a black and white enlarger.

Xerox Phaser 8560 Color not correct PROBLEM: Cyan color is not correct. DETAILS: Light Strip test that prints the 4 colors prints Magenta, Yellow, and Black correctly but the Cyan is not correct. The Xerox web site provided 4 documents that filled the entire page with each color (> Support & Drivers > Phaser 8560 Support > Search Results > Colors are Off or Wrong). After marking where the ink sticks were I printed the Cyan document 30 times and then measured the ink sticks again. The Cyan AND the Magenta used about the same amount of ink, although it should have been 100% of the Cyan ink. I then printed the other 3 colors to see what they would produce. Cyan document: ¾ inch teal strip down the left side and the rest of the document was a darker purple with vertical strips of darker and lighter sections. Yellow: ¾ inch yellow strip down the left side with a light mixture of Magenta mixed in with the rest of the document consistently. Magenta: ¾ inch yellow strip down the left side with the rest of the page a darker red. Black: ¾ inch green strip down the left side with the rest of the page a mixture of black and green. From the ?Service Usage Profile? from the printer: BEFORE 30 Cyan pages: Total Previous Colorant Usage Cyan=37.54 Magenta=36.35 (Yellow & Black had very minor changes) Printed Total Pixels Cyan=1,784,693 Magenta=1,773,124 AFTER 30 Cyan pages: Total Previous Colorant Usage Cyan=50.85 Magenta=40.06 Printed Total Pixels Cyan=2,299,550 Magenta=1,901,358 Color has not been adjusted in the printer or in the software. Total Pages Printed on Printer: 2,437 http://www.support.xerox.com/SRVS/CGI-BIN/WEBCGI.EXE?St=154,E=0000000001799320691,K=9884,Sxi=15,Solution=obj(1966)


the problem is not with the printer but it is with the ink that might be damaged, this is located inside the printer
