Softproofing
« on: July 29, 2010, 08:13:20 am »

I'm trying to get profiles from the Colorburst Rip to show up in Photoshop CS4 or 5 to softproof. They are made as 6 color and so far I have not been able to have them read by PS. Does anyone know if this possible or am I out of luck as far as softproofing goes. The rip is running an Epson GS6000 thru a pc but they are working on Macs and then sending the files to the pc.

Why are your profiles *6-color* profiles instead of the usual CMYK profiles for ColorBurst and the GS6000? That's likely the problem as I don't believe PS is going to handle a multi-channel profile without a plug-in designed to add that capability.

Even in the case of the 11-12 ink Epson 7900/9900 printers, ColorBurst (and most RIPs) will still treat it as a "CMYK" device. (the conversion from CMYK to CcMmYKkkRGB is handled at the driver/device level just like a standard print driver will do the same from RGB).

If you've got an "HM" mode for the GS6000 via ColorBurst, use that and you'll have a nice CMYK profile that you can use in Photoshop. Only catch is, as I'm sure you've already discovered, is that you'll need to place a copy of the profile from ColorBurst's default location to a place where Photoshop will have access to the profile.

That's how Colorburst makes its profiles for the GS6000 - 6 color. What is HM mode? I placed a copy of the profiles into colorsync  so PS could see them but it is not, probably because as you stated they are 6 color.

6-color huh? Weird. I've plenty of experience with ColorBurst....just never with a GS6000 obviously.

"HM" is a special mode in ColorBurst available for a few printers that's essentially a "driver" CMYK mode...it disables all the light curve controls, channel limit controls and ink limit controls. You basically just select the media type (that's going to control the ink limiting) and profile it. I believe this mode still allows linearization with the Epson 11880 but it disables linearization on the 7900/9900. I just checked my version (Mac X-Proof) and it appears that HM mode is only available on the Epson 11880, 7900 and 9900. It's a great "non-color geek mode" if you want all the color management control but simply want to profile it more like you would with a RGB driver...except that it's still CMYK so you still have the advantage of customizing the GCR, black limits and total ink limits...unlike what you can do with a RGB profile.

Sorry I can't help you more on the multi-color profile issue.

CS4/5 Customize Proof Setup can’t “see” multi-color profiles. You can however soft proof them somewhat using the Convert to Profile dialog/Advanced mode where they are accessible. Just have the Preview check box on. You’d have to actually convert the document if you wanted to view it without the Convert to Profile dialog open. That makes editing the image in the original working space not possible. I’m not sure why such profiles don’t show up in Proof Setup (I’ll have to mention this to the team for future versions, not that mult-color profiles are used all that much).

Thank you. I just wish there was a way to soft proof out of CS4/CS5 on the Mac but I guess there isn't. Colorburst on the GS6000 is different than on any of the other Epson's. Thanks everyone for answering my question.

There is a way... but it might not be what you are looking for.  The ColorCast module of ColorThink has the ability to place the effect of one profile into the framework of another.  You can take your 6-channel profile and embed its effect into a more simple RGB  or CMYK profile.  And then use that profile to soft or hard proof your work.  There's more information on this in the manual:
http://www.colorwiki.com/wiki/ColorThink_P...rCastTM_profile

ColorCast is an additional module that has to be purchased in addition to ColorThink Pro.

Thanks Patrick, I'll take a look at it.

I use the ColorThink/ColorCast module on My Mac for the multichannel profiles that I make from Ergosoft's ColorGPS and it works quite well.Also the ColorThink application  is quite interesting to use on it's own!
