 Design For Print Photoshop

We can reproduce a wider range on screen than we can in print, RGB spectrum is bigger than CMYK.

 Photoshop will covert the colour we cannot get to a new colours that it sits in the nearest place in the CMYK colour.The issues with working in RGB mode is that we cannot print these colours accurate, but files sizes are smaller in RGB so its photoshops default mode.

Gamut Warning shows the pixels we cannot get in CMYK, they sit too far outside the range. This gives us an idea of what change when we print or convert the image. This shows there will be a colour shift.

If we want control over the change we can make adjustments to brightness, contrast, saturation, hues, but these are also application that can push out colour from the range of colours printable. Turn the saturation down in Gamut Warning to take control of the printable colours.

The colour range tool can be uses to select only part of the image that needs changing, select>colour range, it better than the magic wand as it more selective. We just want to work on the colours out of range, so we select out of gamut option, this selects just the pixels we need to work on. Apply the adjustment to just the pixels that need it. Just this is you don't know where the images come for or how they are edited eg a mixed content book.

select>colour range>sampled colour 

The second idea is used if you are taking the photos or you're scanning in images, go to view>proof colours, this changeS it so your are working in RGB but the image is a preview of the CMYK. Do this at the very start so that all the colours fit inside CMKY range when editing. Changes the format of the image, bets of both worlds as it smaller in RGB but will print as seen. Use this for photoshop images or editing images. APPY THIS TO THE IMAGE FOR THIS BRIEF TO SEE IF THEY WILL PRINT

Gamut Warning applied to image for this brief 

Spot Colours

We can pick with pantone colour ween for the book by selecting the book and typing/finding the name. When it types it selects the corresponding colour. Alot of spot colour aren't CMKY so it'll probably have the warning sign. The colour is defending by the mode of the colour, so if this is added to a RGB it coverts it, it not taking advantage of the fact spot colour can be produced for accurate reproduction. Its very primitive way to chose a colour, no link between the colour choice and the printed colour, the link between the unique colour number is lost therefor cannot use this way as printer/digital world cannot link. DON'T USE THIS

The pantone number need to always been seen in the digital process so the printer knows what shade to use.
