SuitAble File typeS
PDF is the preferred file type for print. This should be created using high quality print or press quality,
with all fonts embedded. Scanned images should be minimum of 300 dpi. Transparency effects need
to be flattened. Bleed to be included if required. Files for magazines, books etc should be supplied as a
multi-page pdf, not readers spreads or printers pairs.

Flattened tiff or jpg files are acceptable, but note text and graphics will be bitmap rather than vector
quality. All files should be saved in CMYK.
Please note supplying Microsoft Word, Excel, Publisher, PowerPoint files for print can result in file
errors and colour shifts.
Be aware that when conversion or software errors occur, there may be a charge for putting the files
right. You will be notified in advance of additional costs that would be incurred before we proceed.

ConvertinG rGb FileS
If we have to convert your files for CMYK printing, RGB colours used in your file may suffer from
colour shifts due to CMYK conversion prior to printing.

AddinG bleed
Bleed is a printers term for colour that is printed outwith the required finished size. Due to cutting
inaccuracies to industry standard tolerences, illustrations that spread to the edge of the paper can
leave white edges of unprinted paper. This can be avoided by ensuring that the artwork extends
beyond the finished size. We require a bleed of 3mm. Also, it would be a good idea to keep any text
or image at least 3mm from the finished edge.
When using large areas of solid black, the colour breakdown should be 100% black, 50% cyan to get
a more even ink coverage. 4 colour black should be avoided as it can cause other areas of single black
to appear lighter.

Client HArd Copy
A client proof supplied with the file is the best way for us to check that the content of the job being
printed is correct and that nothing has gone wrong in the conversion to print process.

Colour MAtCHinG / pAntoneS
There are a large number of variables which can affect the colour produced in printing. Looking at
colours on a monitor, especially if no monitor calibration has been carried out, is unlikely to produce
the same printed result. Also un-calibrated desktop printers, willl produce very different colours to
those produced on a professional printing press. For colour matching we recommend that colours be
chosen from industry standard pantone references book.

Colour
All computers, scanners, digital cameras and monitors generate their images using RGB (Red, Green
and Blue). Our colour presses use CMYK (Cyan, Magenta, Yellow and Black) also known as process
colours.
Conversions from RGB to CMYK are best done in Photoshop and this should be completed before
the file is sent to us.
Any RGB files sent to us will be converted using industry standard RGB to CMYK conversion but this
can mean that some colours may change dramatically on final output.
If specific pantone colours have to be achieved on final output this should be intimated to our estima-
tors or print reps.
Some RGB and Spot colours are “out of gamut” from their CMYK equivalent. If this happens you will
find the closest equivalent CMYK colour may look very different from the colour you intended.
Avoid using tints that contain less than 10% Cyan, Magenta or Yellow as they usually print much lighter
than they appear on screen, also large areas of the same dark colour (ie solids) can lead to uneven ink
coverage and extended drying time.

SCAnned FileS
When scanning photographs it is best to save them as either EPS or TIFF files as this preserves the
colour and sharpness of your image.
Scanning a printed item from a magazine or book may lead to a moiré effect in the printed output. It
is best to ‘de-screen’ the image or blur it slightly to avoid this. (See your scanning software and hard-
ware manual for more information).
Saving in GIF or JPEG formats compress the image which loses information creating changes in colour
and sharpness.

WorKinG WitH text
Small text is best produced using a single colour of ink. All printing presses vary when laying down
their different colours of plates which can lead to fuzziness on very small text. Also when knocking out
white text from a solid background, small, fine or thin type should be avoided as it may “fill in” on final
prints. Watch when putting text over a photograph as it may be hard to read. Try lightening the image
to overcome this problem.

FontS
If you are not supplying a “Press Ready PDF” to us it is best to supply the fonts and images you have
used in your file.

Multiple pAGe doCuMentS
Create a separate page in your artwork for each page of your Booklet which then can be submitted
to us as a multi-page PDF.
Please do not supply us with ”printers pairs” or “readers spreads”.
Add 3mm bleed all round
Allow for creep (see below)
In a saddle stitched booklet the thickness of the paper causes the inner pages to extend beyond the
outer pages when folded. This means when trimmed to finished size the inner pages are narrower
than the outer pages so it is best to keep text or non-bleeding pics well away from the fore-edge of
the page to allow for this. Remember the thicker the booklet the smaller the inner pages become.
