General File Handling.

  • Files written to disk must be ISO 9660 standard.
  • RGB must be used, not CYMK.
  • Files off a Mac. must have a file ending ( .jpg, .tif, .psd, etc ) and should be burned to disk using writing software such as 'Nero burn'. Do not use the Mac.'s own CD burning system as files may not open.
  • Floppy & Zip disks must be IBM / PC formatted
  • When scanning / resizing, all images should be set to 300dpi at the required output size.

COLOUR MATCHING:

If colour is important, some form of sample must be left otherwise it is at the discretion of the printer.  Even if the image has been printed before, there is no guarantee that the colours will be the same as previous.

 

Working with TIFF format files.

Work on your digital images as much as possible in Tif format to avoid loss of quality during JPG compression.  For Larger images, save a copy as high quality JPG format for printing, but keep yourself a Tif copy.

  • DO NOT save tif files with Layers or Compression.  Flatten any layers before saving if working with PSD Photoshop format.
  • Files must be RGB (NOT CMYK)
  • Always save as 8 bit
  • Save in IBM PC format as shown in the tif save options.

  • Do Not save using 'progressive' or 'optimized' options.
  • Files must be RGB (NOT CMYK)
