Preparing artwork for digital printing
PROCESS (CMYK) COLOURS
All CMYK jobs must be in process colours (in Quark Xpress, make sure that the tick box marked 'Process Split' is switched ON for all CMYK colours). EPSs must also be checked for CMYK in the programme they were originally created in.
All special, spot colours must output as process split.
REMOVE ALL UNNECESSARY SPOT COLOURS, especially: RGB default colours in Quark. This avoids confusion when outputting plates. They are easy to spot, if you go into 'Print' and select 'Separations' then go to 'Output', this will give a list of all spot colours made.
Remember to check all EPS files.
QUARK XPRESS & TRANSPARENT PICTURE BOXES
Avoid using transparent picture boxes wherever possible for colour or grey scale pictures. This can cause jaggies or stepping to appear on the edges of scanned pics when outputting.
TRIM & FOLD MARKS
We recommend using Quark's own registration marks and NOT manually created ones, with all fold marks to be a thickness of .25 mm, coloured 'registration' and positioned 3 mm from the trim.
In most cases black type/objects should 'overprint' the colours under them. This is the default in Quark, but check anyway, otherwise it will lead to register problems (a particular problem when using Freehand/Illustrator).
WARNING: Overlapping drop shadow text or coloured text over a scan does not automatically knockout/choke or spread/overprint colours under them, in fact Quark creates illogical trapping in these instances. You need to highlight the text and manually correct it using the 'Trapping Information' palette.
Please include 3 mm bleed on all bleed pages (Consult with us for perfect bound covers).
IMPOSITION & MULTIPAGE DOCUMENTS
Please create files using single pages as this will enable us to impose your document for print.
Please create and name customised hyphenation & justification settings, rather than manually adjusting the default setting.
FONTS & STYLES
Avoid applying pseudo styles to screen fonts (bold, italic etc.), it is much safer to choose an actual printer font that exists in your font library.
With files supplied in Illustrator, Freehand, Corel Draw, Publisher, Word etc., please turn all fonts to 'paths' or 'outlines', especially if created on a PC.
