    Does input profile detection ever work?

    98% of the time this is a moot point, because people usually send us files using SWOP as the output intent, but when that is not the case, I've not found any way to make the RIP use the incoming document's output intent. The manuals are contradictory, but the ColorPro User's Guide says that: A...

    Where can you purchase printed Gracol targets?

    My Google-fu seems to be weak today; I can't for the life of me find anyone selling hard copies of the ideaAlliance G7 forms. Anyone have a link?

    Color management with lamination

    We're looking at expanding lamination options, and I'm concerned about color matching. Does anyone have good advice for dealing with this? Specifically I'm concerned that: #1 -- The gamut may be different between gloss and matte. We limit the gamut to Gracol Coated v2, but I'm not sure that...

    Bad color conversion for DeviceCMYK images

    I'm looking for a work-around to a problem with converting DeviceCMYK images to gray. The rip produces gray images with any value darker than about 40% as straight black. I can get correct conversion by assigning the output intent profile directly to an image in the PDF, but I'm looking for a...

    Black vectors forced to gray

    I'm dealing with an issue were in a B&W halftone-RIP pages that have multiple color spaces can produce pretty odd results. Basically, if we have RGB black or just straight black in gray only mixed with a CMYK marking that is a rich black, the rich black seems to become the new absolute black and...

    What's a realistic light coverage limit for an Oce?

    Got some complaints over highlight blowouts on work off of a 6250. Printing some test strips, it looks like the machine can't reliably lay down below 6% coverage at 125 LPI -- which is the default. Is it realistic to expect better? This machine is a year and a half old, but maintenance is all up...

    Printing solid images to a DocuColor

    Does anyone have experience trying to print fully-variable images to a DocuColor at rated speed? I need to print full-sheet images to a DocuColor 5000AP with FreeFlow server and not have the machine bog down. Currently, it print at about 1/5 rated speed. Again, these are fully variable images...

    Paper warping

    I started this thread in finishing and didn't get a response, so hopefully I'll have better luck here. We have a process where book covers are printed on Docucolor 5000s, and then laminated with nylon. On sheets with uneven coverage, we get paper warping where the sheet at high-coverage points...

    Uneven cover curl after lamination

    I'm having trouble with sheet warping for digitally printed, nylon-laminated covers. We use docucolors to image and are pretty happy with the quality, but when coverage is particularly un-even, the sheet shrinks in high-coverage areas and causes waviness. Laminating then kind of "seals" in the...
