    PMS vs Spot best practices for various presses

    I'll just say that I have never been a fan of this at all. In fact, my usual response to people who ask about these procedures/processes -- and yes, most RIP's have some version -- is that all of them are basically work-arounds for inaccurate profiles. When reproducing color with a printing...

    PMS vs Spot best practices for various presses

    Here's the way it works: Any spot color is any RIP is two things, a name and a L*a*b* value. In just a quick check in Photoshop, the L*a*b* value for Pantone Black in the Solid Coated library is L=17 a=1 b=3. So that L*a*b* number is what the RIP will attempt to locate in the destination...

    Smudge lines left on some prints Canon ipf8400

    Maybe so... But as far as I'm concerned, the ipfx400 is the best printer ever made. I have one myself and if the goal is absolute top quality, nothing else can touch it. Mike

    Smudge lines left on some prints Canon ipf8400

    That's what's known in the trade as a head strike. The media is buckling in that spot for whatever reason and the printhead is hitting it as it passes over it. On the ipf, usually that caused by too much ink for the media, so the media cockles and that causes the buckling and the head strike...

    Best Grey neutral wall paint.

    Just about anyone who sells paint in the US can match any color you bring them. Have you tried just tried taking a swatch of whatever color you want to paint store and having them match it? Mike Adams

    Profiling a Canon imagePROGRAF PRO-6000

    DYP, The problem with all of those is that none of them actually change any of the internal inking configurations. They make them somewhat easier to sort through for various third-party media, but they don't add any settings that aren't already there. No paper manufacturers are able to get into...

    Profiling a Canon imagePROGRAF PRO-6000

    Try a heavier-weight material. The heavier the material the more ink it's likely to take. That's about your only hope in the front panel. The problem is that on all these aqueous machines that can profile "RGB" the inking settings that are built into the media in the front panel were made for a...

    Profiling a Canon imagePROGRAF PRO-6000

    The issue you're having is what's known as "capping." Basically capping happens when an inking condition is created in which the single channel ink limits are set so that they can't be supported by the multi-channel ink limits, so that in certain conditions, the profile then "caps" and just...

    Pantone Coated vs Uncoated Corporate style guide issue

    I don't doubt they were happy with 021. What I would have suggested to this client is that they use 021. Period. Which is precisely why you shouldn't be creating a Rube Goldberg device of a style sheet in the first place. You may have gotten a passable result, but that won't happen every...

    Pantone Coated vs Uncoated Corporate style guide issue

    Well... All that aside... If I'm understanding your process here: They really want 1505C. You've told them 1505C isn't possible by differing printing methods and have therefore steered them to 1645C, which they have grudgingly accepted, but don't like on uncoated stock, so for that you're...

    Pantone Coated vs Uncoated Corporate style guide issue

    Alternate thread title: I am hunting a unicorn. Where is a good spot to start my search? Sorry, but you're doing your client a horrible disservice here. Instead of chasing imaginary creatures for them, you need to sit them down and tell them what is realistic in the printing industry. None of...

    Can't wrap around my head what causes this...

    If the images with the shadows themselves are raster images, and the backgrounds are vectors, then this is most likely caused by the incoming profile rendering intent settings in your RIP. Probably it has raster images set to use Perceptual, and vectors set to use Relative Colorimetric. If all...

    Help with RGB color on a sign

    IT Supplies, As a guy who makes a living as a "color specialist" I do have to point out that this is not the way it works. A color is either in the gamut of a specific machine/media/ink/resolution combination, or it is not. The first key is to make a profile that captures every bit of the...

    Looking for Specific Printers (Ricoh, Mimaki, Oce)

    John, Are you absolutely certain? Because that's not my understanding. My understanding is that the Ricoh is simply a rebranded Mimaki and there are no differences at all, including ink. Also there are very, very few of these machines out there. Very few Mimakis, that is; Ricohs, even less...

    Mimaki CJV-300 - color correcting a custom profile

    Chris, The thing I'd attempt to impress on you is that "matching" one profile to another profile isn't the way it works. It's a fool's game to try. The idea of profiling is basically to create a machine state -- the inking controls that are RIP specific -- and then to characterize the...

    Looking for Specific Printers (Ricoh, Mimaki, Oce)

    I'll admit to being a little curious here. At one point or another I've profiled various materials on all of these printers at various locations using various RIP's, and I'm curious if you're giving any consideration to anything other than printer model in your "performance study." I can tell...

    Mimaki CJV-300 - color correcting a custom profile

    To be frank... Profile-making is an art more than it is a science. Honestly, if you feel the need to look for answers online, I'd say your level of expertise might be your biggest issue. However, I would point out that "grey balancing" is most definitely not your issue. Properly made ICC...

    Help with RGB color on a sign

    Given the image you posted, if the question is if that exact color is in the gamut of any outdoor signage-type inkjet printer... The answer is no. However, you may be able to get close enough to satisfy the customer. The right track is to not 'convert to CMYK' before printing, but to send the...

    Demo copy of Fiery XF?

    Does anyone know if such a thing exists? So, I've been in the business of large and grand format color management for 14 years now, and the biggest change I've seen in the market has been that when I started, stock profiles were universally terrible and it was hard to get a good many raster...
