honor, preserve, replace, ignore - trap settings in a RIP
honor, preserve, replace, ignore - trap settings in a RIP
I got a problem with illustrator files. When do trapping myself in illustrator (overprint stroke) my harlequin rip doesn't keep it but in all others application (indesign, quark, etc...) it works very well.
Can someone help me??
While I do not have access to the version of the RIP you are using, there are different ways to process settings - trap objects might actually be in you PDF - but the rip has the ability to "honor, preserve, replace, ignore" these trap settings. That would be the FIRST place I would look. Clearly, the overprint setting is ON in the file, but that does not mean it will be parsed and applied.
in your simple example, you clearly could fix this example easy enough by making the stroke be 100 yellow and 100 cyan - then you would not need to worry about if your rip can honor only the stroke overprints -- but this may not work when the type transitions over other colors, as i am sure you already know !
Second - since Adobe Illustrator can export PDF/X1a - and as I see that the PDF example file you supplied is NOT a PDF/X1a file - you might try exporting to that and see if that triggers your rip to process these overprinting strokes that you are using to trap.
Third - If you are printing from Illustrator, note that in the Print Dialog box, if you select as your Printer --> Adobe PostScript file - note that there are three (3) Modes...Composite, Separation (Host Based) and InRip Separations --> you might try all of these to see if that might trigger you RIP to honor the overprint settings - I forced overprint (i think) by opening that PDF file in Illustrator, saving it as an EPS file - and then opening that EPS file in Acrobat and saving it as a PDF/X1a file (attached) - I am not recommending that approach, but it would be interesting to learn if that changes the stroke object into something your RIP honors...
Forth - have you tried outling the type ? It may be that the rip can't figure out the font properly and is simply ignoring that the type has a stroke set to overprint - perhaps converting the type to outline?
Anyway, these are some of the ideas - hope one of them helps.
