Printing Process

Incredible technology. An exceptional output.

At MILK we understand that quality printing of your precious images is of utmost importance. Just as you do, we want these images to last and that's why all photo books and albums are printed digitally onto premium, archival papers, using industry leading HP Indigo Printing Presses.

Your life in color

  • The liquid-ink digital printing technology we employ (HP electroink) enables fantastic color and print quality, with consistent results, similar to and at times surpassing conventional offset printing and exceeding the quality achieved by competing digital printing technologies.


  • To achieve a print result as close as possible to your original images we use an innovative wide-gamut RGB workflow. This makes use of HP Indigo's entire color gamut rather than simulating the results of a conventional CMYK offset process. The result is more vivid, saturated colors and smoother skin tones and gradients.


  • The Classic range are printed in 4-colors (cyan, magenta, yellow, black), whereas books in the Premium range are printed in 6-colors (cyan, light cyan, magenta, light magenta, yellow, black).


  • The HP Indigo's liquid ink binds itself to the fibers of the paper, rather than sitting on top as with toner based printers, this means the paper chosen will retain its physical characteristics (whether textured, coated, or un-coated).

Key things to note

  • Your images will appear slightly different when replicated in print than when viewed onscreen due to the differences between RGB onscreen viewing and CMYK printing.


  • Very bright colors can appear slightly more subdued and the overall result may be slightly darker in print.


  • Our RGB workflow supports wide gamut profiles including Adobe RGB and ProPhoto RGB as well as the standard sRGB. Images should be uploaded with the profile embedded.


  • Images should be high-resolution. We recommend aiming for an image resolution of 300dpi at the final size. Our software will alert you if this drops below 160dpi due to the image template chosen.


  • Paper choice is a very important consideration when selecting the right book format for your needs. See the related article Discover papers for more info on the paper options for each format.


  • Black & white images require more careful monitoring. If your book consists of mainly black & white images, please notify us immediately after placing your order, quoting your order number.
