Like Mike, a lot of people in Printing and Graphic Arts as well as Graphic design and Photography, get annoyed at questions like this but we're are not alone in having our skills 'dumbed down' by what technology supposedly offers. At the moment you probably don't have a 'trained eye' let alone...

Digital presses are notoriously variable and even though you are calibrating each press to the same target there will probably be visual inconsistencies between them. As a result, the preferred method of matching spot colours on a digital press using the Fiery RIP with the Graphic Arts Package...

As Stephen implies, if you want to simulate the result of printing on the yellowish stock you need to convert the RGB image to the profile of that printing condition first. You can then print that profile using the Absolute Colorimetric Rendering Intent to the designated output device (printer)...

Good for grey balance

That depends on whether you're on the equator, one of the Poles or somewhere in between.

Stephen, I believe your demonstration only highlights what happens to untagged files when they go to different devices. Why don't they just send them a tagged, as in ICC profiled, CMYK file and see what they do with it. Their RIP will have a much better idea of the colour that is supposed to be...

The links to the articles posted by Stephen give plenty of historical background to the use of UCR/GCR but another paper by two Swedish researchers indicates that there is very little difference in the implementation these days (see link below). As the articles report these separation techniques...

The ISO 12647 family of standards, especially 12647-2 and 7, have been very well accepted and in a relatively short time so I don't know why you don't consider them useful in the 'real' world. Quoting ISO terms and definitions has nothing to do with dealing with an upset customer That's usually...

Stephen, good link. Gordo, while they might be often described as 'levels of grey' they do have something to do with colour in the context of a colour reproduction system. Manishbjain, you are confusing the 256 'levels', or shades, of a specific channel (R, G, or B) with the graphic...

ISO 12647-7:2013 Proofing processes working directly from digital data' provides the following description: "The purpose of a proof print is to simulate the visual characteristics of the finished production print product as closely as possible." It includes the specifications and tolerances for...

So much for 'standards'.:( Mark Stegman

Seems an odd way to go about this. Sounds like the printer has only read half the manual. As previously stated you need the reference data to generate a profile from a printer target but giving you just one is pure folly. As any pressman will know the printing press is something of a 'beast' and...

As Dov describes in detail working with PDFs made from MS Office is fraught with danger and ensures only one thing... The longevity of the working life of the Prepress Operator with the skills and knowledge to sort them out.

I doubt Trapping would work as text would have to be printing alongside another colour. If there was no background then there would be no effect. Trapping also usually applies the 'spread' or 'choke' to the lighter colour. You can customise the effect and reverse the setting but it's still a...

I am not sure that industry doesn't want consistent press performance but there are just too many variables that are hard to control to achieve some sort of ideal state. That's why we have tolerances in the standards and specifications for different substrates. Essentially, it's much easier to...

My guess is that the RIP might be treating the Spot as opaque and not transparent like all process colours. I'm not a flex expert but this could produce the effect shown in your screen capture especially if the black was printed on top of the PMS. My questions is... Why do you want to overprint...

I'm not sure I'm getting. In other words, the text is treated as a 5th 'colour', or separation. Yes? Why? It seems to me that you are adding expense to the workflow in doing this by requiring an extra plate. Why not just create language specific black plates for each 4-col set? The printer is...

Gregg, As Kyle says, going to that Menu will allow you to override whatever profile has been assigned to your image(s) just as Right-Clicking on the selected image, hoping to Graphics > Image Color Settings will but probably a better way of handling this is through the Color Settings dialogue -...
