Maybe we'll see if the printer could just output a duplicate separation of the color channel we're trying to use and call it their varnish plate?!? We do wonder what standard practice is, though. And we have to bring all of this into the master document and make sure it aligns perfectly with the master art. If there were any of the stitching issues we see a bit, depending upon preview, that wouldn't be good. I'm not really sure to what degree something this complex would be to the printer. But I'm guessing it must be a similar process. It's not exactly the same, and does show more of the hairlines sometimes seen in Acrobat if display preferences aren't set properly ('stitching' issues). It actually creates a very similar file, with hundreds of individual clipped embedded images. So on a whim, I tried printing separations to a postsript file (just the channel we want) and running it through Distiller, then back into Illustrator. There are a number of elements that extend outside of the bounds of the design as well. It does create an incredibly complex web of hundreds of small clipped black & white embedded images (I'm assuming they're 100%/0% K). I downloaded a trial for InkQuest, then generated separations and released the separations for the channel we wanted to replicate. If this is not possible, and other methods to try? Converting the vector elements to knock-out wouldn't be too hard, but the raster images with soft edges are a bit trickier to figure out. Is there any way to convert this 'preview' into an actual Illustrator mask that could be added to the file for the printer? We would end up making the entire mask a solid spot color for the varnish. It has all elements that need to be knocked-out done so properly (including anti-aliased image edges), and even some areas that will overprint (and we would like the matte mask applied to) not knocked-out. When I do a separation preview, and only view the single spot color we need the varnish applied to, it looks like an almost perfect mask. So the mask will be semi-complex, and we're trying to figure out the simplest and most accurate way to create it. You should use 300ppi resolution in Photoshop (go in the menu 'image' then 'image size'). You don't need to worry about the lineature and angle but only the resolution (ppi/dpi) of your files. All you'll need to do is send your files properly. But this 'background' color has a number of elements over the top of it, from type & vector shapes, to images with anti-aliased transparency (will be CMYK). The color separation itself is done by the printer. Hi, we are doing a packaging design and need to create spot varnish mask for a matte UV coating that will be applied to specific areas of the design.įor the most part, the matte varnish will be applied to all areas of a background spot PMS fill color.
