Bound insert production: Supplying digital files
Approval
If you are supplying digital artwork for us to print, a full size colour proof (including corner trim positions) with full text must be approved prior to production of the digital cromalin.
No changes should be made to agreed copy without the agreement of our publishing department.
Screen angles
Yellow 0° or 90°, Magenta 45°, Cyan 15° or 105°, Black 75°.
Duo tones should be angled to avoid screen clash.
Under colour removal
Minimum 20% in Yellow, Magenta and Cyan. Maximum 220%.
Advertisements containing large, heavy, dark areas, e.g. night time photographs may require a higher level of UCR. If you think this may apply, please contact Publishing on 0118 959 2111 for advice, before colour separation.
Reversed-out type matter should be produced with the dominant colour for shape and size, with the under colours spread to reduce problems with register during printing. Type matter or detail smaller than 10pt should be reversed-out of one colour only. Fine lettering and thin rules in one colour only.
Shiners
A 40% tint of cyan should be laid under all large areas of solid black whenever there are no under colours. The tint should be cut back from all white-out areas and reversed-out type.
File format/images/fonts
Files can be accepted on CD or disk.
Send copies of files not originals.
Label all CDs or disks with the advertiser's name, type of advertisement and identity of the directory in which the advertisement is to appear.
Please supply all files in recognised page layout application format (e.g. QuarkXpress/Pagemaker). The preferred file format is PDF. Alternative file formats are Postscript and EPS.
All files must be complete, fully-assembled pages with high resolution graphics in place. All fonts and images should be embedded.
Pages should be assembled as single pages and should be consistent in dimensions and margins.
A minimum bleed margin of 5mm is required on work that prints to the edge of the page. Each file (page) must be 100% of the final book size.
All files, including any placed graphics, must have a unique name.
Create image backgrounds of white instead of none.
Do not use pre-defined hairline rules; they should be defined to no less than 0.25pt.
Do not include trapping within the file.
High resolution images should be supplied in TIFF, EPS, JPEG or CT format, with only lossless compression used.
All images must be in CMYK (Cyan, Magenta, Yellow and Black) format (and Pantone® if required) not RGB (Red, Green and Blue).
