Converting from RGB to CYMK

[rutabowa]

It doesn't matter what they look like in RGB (unless you have a proper calb' screen), work in CYMK and make use of pantone palettes. Learn the basics of DTP and printing, then you'll save your self an awful lot of agro

Unless you have a calibrated screen CMYK and Pantones will look wrong too. You could use Pantones in conjunction with a (very expensive) book of Pantone swatches, then you'd know exactly what colour you were going to get (relying on the printer to be accurate anyway).

Working in RGB (as opposed to CMYK) is better for adjusting complex colour images (ie photos), because the adjustments you make can be more subtle (as there is a bigger gamut).

For images actually, work in RGB until the thing is ready to go - then convert to CMYK. All stuff arrivnig at the printers should be CMYK format. With DTP progs use Pantone Guides and import colour using the correct pantone numbers - regardles of how it looks on screen. Screens being RGB and all... Avoid 'mixing' artificial colours using the palette wheels - except the basic cyan, magents, yellow, black (CMYK - k standing for 'key' colour in print terms).

That is what I meant. I managed to pick up swatches quite cheapily from a uni's clear out - think they were about a tenner a shot. Work also got me a load of swatches, but of course I had to leave them when I left my job. Made my work SO much easier! But I found working in CYMK from the start easier (if you have the swatches).

Never had a problem with printers so far *touch wood* - although I did cock up when printing from the Epson 10600, but that was my fault

that's a bargain! tho strictly yr meant to replace old ones cos they fade in sunlight etc...
what i'm not sure of is... if yr working with Pantones, then whether yr working in CMYK or not becomes irrelevant, doesn't it? I mean, a printer will print all the stuff that's in CMYK with those 4 CMYK plates, but every Pantone you use adds an extra plate to that, doesn't it? (cos they're premixed inks). So it becomes more expensive with every extra colour. If you use Pantones then print to a CMYK printer, the printer will just produce a CMYK approximation of the Pantone (which can be very different to what you intended).

I'm learning...so please carry on.

fancy giving a step by step to CMYK for printing for photographs..I've got some stuff to get vanity publish in the near future..I've seen some printers help and some fkk things up..."Thats what you gave us..." sorta thing.

i work mainly with photos... we have colour calibrated screens, and matched CMYK profiles with the printer. Without that, you'll just need to get a laser proof from the printer before they print the whole run, the colours should match exactly what you get back from the printer in the end. They might charge for this.
