Is it possible to make a profile or something that can substitute for a missing profile knowing just a few data points? I'd like to make something that stands in for a Extended Gamut (CMY + OGV) profile. I know the white point, the black, and the LAB values for the 6 "primaries". I'd like to...

I need to produce a printed color chart. I have the colors in a spreadsheet, defined as LAB coordinates (D50). As opposed to starting with photos or scans of the originals. My first step is to figure out which of the colors are printable in CMYK. I plan to use the Gamut Tool in PatchTool, which...

Would anyone be able to name any commercial printers that are doing sheet-fed jobs using "XCMYK"?

I'm a graphic designer, not a press operator. I know the basics of offset 4 color lithography. I'm studying up on color management practices. Some of what I'm relying on was written with press operators, not graphic designers, in mind. In particular, I see, over and over, passing references to...

I've designed a swatchbook illustrating the colors achievable in the GRACoL ICC Profile color space. I'd like to self-publish it, and so now I need to get it printed, and its going to be, by my standards, a big job - ~$100,000, I estimate. I'd like to find a North American printer who wants to...

I've been asked to bid on the creation a marketing piece for a manufacturer of fine art inks. They want it to include a color chart, as accurate as possible with 4 color offset litho. Their actual specifications call for it to be "matched to Pantone colors". But I know they want it printed in 4...

Hi, I'm a designer, I'd like to know how difficult it is to bind pages of different widths into a single document. It will be around 250 pages, 8.5 x 11. around 40 of the pages would be 4.25" wide, and they would alternate with the full size pages at the back of the document. Spiral binding...

What is known about whether or not process colors fade more quickly when printed on papers containing optical brighteners? Is there a typical lifetime one could project before you'd expect to start seeing changes?

I am working on a color guide for graphic designers. I have to decide if I'm going to use the 2013 or the 2006 GRACoL profile. I understand that the former is better because it has a more realistic assumption about the colorcast of the paper. However: are printing companies actually using it? Or...

I am designing something to be printed using the GRACoL 2006 ICC profile. Is there an official limit to the total ink coverage (C+M+Y+K) or a good rule of thumb about how much is too much? I'm striving for colorful darks but don't want to overdo it. I have read 340% in various places but would...
