It still feels like rather a long-winded way to get a PDF file with some of the content removed though. Deletion of that kind is relatively reliable.
In that case you might be able to run the file through Ghostscript, telling it not to honour the Optional Content portion, and get a PDF file without it present.Īnother solution (again limited to PDF) would be to open the PDF file with an editing application such as Acrobat Pro, and simply delete the bits you don't want. I suspect they will going by a quick Google. called Photoshop DCS 2.0 (DCS stands for Desktop Color Separation). I'm not terribly familiar with modern versions of Illustrator, but wouldn't it be simpler to save two versions of the file, one with the answer layer and one without ?Īnyway, Ghostscript can honour Optional Content, so if you can save a PDF file ( not PostScript or EPS) from Illustrator, it may be that the layers will persist into the PDF as Optional Content. Spot colors are used for four main reasons: (1) when your client cant afford a. If you are content to stick with just Illustrator you might be able to do something with Optional Content. There is little common ground between the 3, is there a reason to support all of them ?

Part of the problem is that you are apparently trying to deal with 3 different kinds of input, you say Illustrator (PDF, more or less), Photoshop (raster image) and EPS (PostScript). Simulated Process separations, unlike true process (CMYK) use spot channels and regular plastisol inks to generate a full color image. That 'something else' depends on what you are saving it as. PDF, PostScript and EPS don't have 'layers' (PDF has a feature, Optional Content, which uses the term 'layers' as a description in the specification but that's all).Īn application such as Photoshop and Illustrator can have layers, but in general what they export to has to have those 'layers' converted into something else. Your current approach will use the parts of the object which mark process plates, but not those which mark spot colorus, which could give some very peculiar results.

What about DeviceN spaces where some of the inks are process colours ? Eg a duotone Black and Pantone ink. Also 2020 color separation in photoshop pdf plugin download color separation in. Whether you go down this route, continue with what you have, or find an alternative approach, there are a couple of things you need to think about how do you plan to tackle Separation inks with process colour names ? Eg /Separation /Black. If you then uses the pdfwrite/ps2write/eps2write outptu device you'd get an EPS, PostScript program or PDF file as the output. It would be reasonably simple to look at the current colour space and discard Separation or DeviceN space. That device looks at the type of operation, and either passes it on to the output device, or throws it away. If you are a competent C programmer you could produce a Ghostscript subclass device using the existing FILTER device (in gdevflt.c) as a template. Perhaps you could explain what you are trying to achieve with this (ie why are you doing this), and it might be possible to suggest an alternative method. The various levels of gray determine how much of that channel’s ink will be placed on the page in any given spot. Trapping is where you increase the edge thickness of colors that print under the black plate. The separations, individual channels printed in grayscale, are used to make printing plates or screens. The reason is that to do so would lose information the marks defined in Separation or DeviceN space would be lost entirely, and its generally regarded as a Bad Idea to discard random parts of the document. Spot color and trapping is not the strength of Photoshop, but trapping can be done. The simple answer is no, in general you can't do this, and I don't know of any tool which will. I think, from the context, that you mean something more general.
'Image' has a defined meaning in PostScript, it means a bitmap, a raster.
