![]() This method, known as an additive color model, works great when viewed on-screen because the light is actually being emitted from your device. RGB images are made up of 3 color channels – Red, Green, and Blue – that are combined to create every color in your image. ![]() Most of the digital images you see every day use the standard RGB colorspace. (If you don’t need to know how colorspaces work, you can skip right ahead to the next section.) Here’s a quick explanation, hopefully without getting too technical. If you assign an RGB profile to the max render it wont change the numbers, but dont convert when you open it becuase that will.Many image editors can spend a long and busy career without ever needing to use the CMYK colorspace, so don’t feel bad if you’re unfamiliar with the details of how different colorspaces work. If you want to simplify matters just convert from CMYK to RGB and back again inside PS and forget max…once you have that sussed all you need to do is then get max to provide the same render as the file you gave it. Again you may need to change the conversion algorithm to find the best one, and again it may not be 100% perfect, but it should be because your dealing with colours in gamut.(in theory).Īssign to profile maintains colour numbersĬonvert to profile tries to maintain colour look. Now all you have to do is Convert to your original CMYK profile. Now…at this point you will be able to compare the colour values of the render with that of the map you sent from photoshop to max…if they are the same then your a step closer. (max renders wont support profiles)Its important you assign because this wont change the colour values of the render, just its look. ![]() When it comes back into PS, ASSIGN (dont convert) to your working RGB space. You may also need to pick an RGB space that can accomodate the colours of the CYMK file…some might not. My guess is that relative colourmetric should do it, but you may need to change to absolute colormetric. ![]() One of them will convert with the least amount of loss (hopefully none) to RGB. If you have a wander into colour prefs you’ll see that there are 4 types of intent conversion algorithm…holding the mouse over them will give you ther blurb…some will try and match look, some will try and match numbers, some do other things. Ok, so assuming you have a file and know its profile (working or embedded)…ĬYMK to RGB…a conversion…theoretically CMYK fits inside the RGB gamut but that can be upset by the profile of each colour mode. Ideally the file should have a profile attached before you open it and you should have your prefs set to ask questions on all counts of a missing or profile mismatch. You need to be sure of this because PS can assume a different profile depending on how you have your colour prefs setup. You need to ascertain the profile status of the starting CYMK file. Depends how fussy you want to be (its not always possible for CMYK to fit back in RGB because of the different flavours of RGB)…but here’s a quick guide. ![]()
