Supplying files in PDF format

Files to be supplied as high quality PDFs at a minimum of Acrobat 7 (1.6) format. Supplying single pages for single page brochures, wiro/plastic coil and saddle stitch booklets. Supply spreads only for folded brochures and cover artwork only for perfect/PUR bound booklets. All pages must have at least 3mm bleed and crop marks with all fonts embedded. All images are to be high resolution (300dpi recommended). To set up a PDF file that contains a spot varnish see “spot varnish” section.


Supply all files with 3mm bleed.

Trim area

Try to allow a minimum 5mm between the edge of the text and the edge of the page. For perfect bound booklets and wiro bound booklets allow 8mm gutters.


All images must be saved in CMYK are at a minimum of 300 DPI at print size.


Ensure all of the document fonts are embedded within the PDF, or where possible please convert your text to outlines. Fonts must be supplied for printing variable data jobs.

Stroke width

0.25 point is the minimum recommended line stroke width when printing at Impact Digital.

Four colour black

For a solid, rich black, we recommend using the following colour breakdown for each of the following presses:
HP: C30 M20 Y20 K100
Nexpress: C50 M40 Y40 K100 (Coated)
Nexpress: C70 M50 Y50 K100 (Uncoated)


Ensure that you have set up your document to print CMYK.
If spot colours are required, create a new spot colour swatch within your document using the Pantone colour table built within your desktop publishing application, leaving it checked as a spot colour.

Saddle stitched and perfect/PUR bound documents

The total number of pages must be divisible by four for saddle stitch documents and by two for perfect/PUR bound documents. For burst bound documents, the cover must allow for a spine. Impact Digital will be able to provide you with a spine width based on the number of pages and thickness of the stock within your document. For multi-page documents please supply as single pages.


Adobe Illustrator and Adobe Indesign transparencies are a common problem in the whole ‘postscript’ world, and are best avoided. Either render your transparency into an image, or use the ‘Simulate Transparency’ option in Adobe Illustrator advanced print options. Transparencies require Acrobat 7 (1.6) PDF version. See graphic below.


Various dieline templates can be found on our website. When creating dielines using Impact Digital templates please ensure you make a note of the template name or number you are using. Also keep the dieline swatch colour in the file.

Sheet size

The maximum sheet size for our digital presses is up to 325mm x 638mm. For large format printing we can print 1.5 metres wide by virtually any length on a range of different paper, vinyl and synthetic stocks.

Hard copy mockup

If possible it is always helpful to supply a hard copy mockup at 100% if possible of the file that you are printing.

Spot Matt Varnish, Gold or White Print

How to set up your special finish:
Create new spot colour swatch within your document for each print technique and label as per below:
Spot Matt Varnish: “NexPress DryInk clear”
Gold Toner: “NexPress DryInk gold”
White Print: “White”
Please note: If items are being varnished with DryInk clear, they must be set to “Multiply” in the effects and NOT “Overprint” if these items are to appear on top of other printed objects.

How to set up your spot colour:

Create a new spot colour swatch within your document using the Pantone colour table built within your desktop publishing application, leaving it checked as a spot colour.

How to set up PDF for artwork that contains a spot varnish: When creating PDF artwork with a spot varnish, the PDF compatibility needs to be set to Acrobat 7 (PDF 1.6) or higher and the transfer functions option must be on (see below).
