OCE 460 using 256 Ink - Printing on 2nd surface Acrylic - Color matching problems

[Tgngreatnews]

Is anyone else having problem of color matching using a OCE 460 with 256 Ink on Acrylic.

When printing 1st surface the color matching is fine. I use the exact same file printing on 2nd surface and the colors are way off, example: the skin colors become Lobster red. See attached. We used 258 Inks for 6 months and had the same issues.

I am using the only 256 Translucent profile available. Any assistance would be appreciated.

What print mode are you using? We have a 480gt and I know that when we print second surface using hd mode on generic transparent media the colors become way saturated like your example. I figured we needed to make a custom profile to fix it.

You need custom profiles. Some manufacturers have horrible general profiles.

also a translucent profile is generally used for backlit applications so you need to use light behind it to see the correct colors and saturation.

i recommend the barbieri LFP, worth every penny.

Thanks for the reply. I have seen our Color Management specialist from Canon/OCE use one of these. In your experience is this something out users can use or do you need a OCE specialist?

You can use it without oce.

How easy to use depends on the rip.

I use with onyx and caldera. Caldera is easier than caldera to make profiles. But both are easy to use.

It is a profiling issue.

And whether you want to attempt to profile the machine yourself depends on just how much time you want to devote to learning the art of machine profiling.

And as someone who does it for a living, take my word that there's very much to learn in order to make really first rate profiles. There are many pitfalls along the way, many people who will give you some very bad advice, and it's very possible to make a substandard profile and never even know it.

And keep in mind that in this industry, profiles are everything. All any RIP does is convert pixel information into dot information based on what it's told to do by the profile it's using to make the conversion.

Great printer + great RIP + great media + great artwork + bad profile = Bad print.

It's not something to skimp on.

(Edited to add: By the way, the Barbieri is a wonderful device, but it also costs a lot of money. I've done extensive testing on any number if spectros, and the bottom line is that with the exception of the i1IO table -- which is a disaster -- there's no appreciable difference between any of the ones currently on the market in terms of end result, if they are working and used correctly.

You could hire a professional to come in and do your whole color workflow for less than the cost of a Barbieri. Unless you plan on doing a lot of profiles -- on the order of using it daily -- a Barbieri wouldn't be a good investment in my opinion.)
