Hi Richard,
Thanks for your reply.
After reading and then looking up a few things from GWGill, I created a new chart from scratch in PS in ProPhoto using the desired CMYK numbers in the "Fill" - "Colour" process.
I then made a print using "Absolute Colormetric", working on the idea that CMYK colours would be within the gamut of the profile for the specific paper. The results are damn near...!
I am quite satisfied with the result which is more than good enough for the printing I do.
Thank you for taking the time to assist!
Regards
William
When you mention “desired CMYK numbers”, what does that mean, exactly? On their own, as in, without a CMYK profile to go with your CMYK numbers, are literally worthless. They are worthless by definition, in that they literally have no (device independent/Lab) values associated with them. The easiest way to picture this is to think of a large TV shop which has myriad TVs all playing the same thing, yet each individual TV is displaying the same colours slightly differently. Reason being is that they are all receiving (for example) RGB numbers but, just like your CKYK numbers, the RGB numbers are similarly worthless. If an LG TV used slightly differently manufactured LEDs then their colour balance obviously won’t be identical. So even if both sets are displaying R100,G46,B37, or any other RGB value, because they use physically different LED backlights and LCD panels (and of course, different components in the various circuits), there’s no way for them to display identical colours.
If they were displaying sRGB 100,46,37 then the 2 TVs just might have a chance of displaying identical output. They’d need to be calibrated and profiled but at least now the colours are being specified unambiguously and so there’s at least a slight chance of it being possible. It’s the profile which makes the RGB/CMYK numbers unambiguous.
So, you need to specify your “desired CMYK numbers” either with a profile or better still would be to just specify the colours you want in Lab as it is a device independent colour space and there aren’t any variants of Lab, there’s just one Lab space.
I realise from your previous replies that you don’t have a thorough knowledge and understanding of colour management. Without at least a working understanding of the basics of colour management, you will find your request incredibly frustrating and as you already said, you don’t understand what you’re doing wrong. My best advice is to read up on colour management, get a basic understanding of how the main concepts work and you’ll be on your way. Good luck with it.👍
PS: from where or how did you obtain the CMYK numbers you desire?
