Preparing your images for print

Preparing your images for print is very different to preparing them for web. For this, you have to understand how to sharpen and make certain adjustments to images.

In this Post Production class Karl shows you his techniques for preparing images for print using Photoshop. You’ll learn what sharpening is and how to apply it, why colour profiles are so important when it comes to printing, when and how to add noise to an image and also when to add adjustments such as curves or levels.

In addition to showing you each step in Photoshop, Karl also visually compares the printed results of four different adjustments, clearly showing the effect of each and revealing the best techniques for enhancing reproduction quality.

This Photoshop class covers the following:

  • Printing digital images
  • Sharpening images using Photoshop
  • Colour profiles for printed images
  • Adding noise in Photoshop
  • Professional advice for preparing your images for print
  • Visual comparisons between printed images with different adjustments

If you have any questions about this class, please post in the comment section below.


Key concepts:

Sharpening images using Unsharp Mask.

Photoshop Unsharp Mask

Increasing the apparent sharpness of an image can help enhance the reproduction quality of an image.

Sharpening images by adding noise.

Photoshop Add Noise example

Adding noise is another technique commonly used before printing images.

Testing and comparing results.

Printing images example

It’s worth printing tests of various settings to see what combination works best.

  1. Karl, I print so infrequently that I am never really comfortable with making adjustments just for printing so your lesson is very helpful. That being said, it seems like I have more issues with luminosity than sharpness, printed images always see 1/2 to 1 stop darker. I have always attributed that to the difference between a monitor (which emits light) and a paper image (which reflects light). Do you run into this?

    1. Hi Bob, yes if viewing on a high contrast screen like an imac fro example. If viewing on a calibrated Eizo or other high quality proof screen then the prints look 95% like the screen although the viewing conditions of the prints also have a huge impact… For example I got some prints back from the lab the other day and I thought that they looked a little dark until I took them closer to the window and realised it was my office that was dark! 🙂

  2. Nice tutorial! I’ve been using noise as the last stage of photoshop composits for years. I use another method though: I fill an empty layer with 50% gray and then change te blend mode to softlight. I then turn the layer into a smart object and add noise using the camera RAW filter. This has beautiful noise and gives control over the amount, size and roughness of the noise. And of course you can change the opacity of the noise layer to change its effect.
    Works like a charm!

  3. I really enjoy that and the information that gave us . and may me feel I need to look into getting myself a new screen thanks again Karl
    P/S your lens on that shoot was dirty show up on r/h side two big marks
    take care Frank

    1. Hi Jorge, No I don’t but there could be occasions with special book printing that has a 400-600 dpi that you would want to.

  4. Hi Karl,

    Excellent video. I was looking forward to something like this.
    Question: do you ever use High Pass filter in an overlay blending mode to sharpen your images? How does your method compare to high pass?

    Thanks a lot in advance.

    Jorge.

    1. Yes I have and my associate Tim Flach uses an automated version via actions of that for some of his work. There are also some independent plug ins for sharpening that people swear by and from what I’ve experimented with it’s useful being able to adjust some of the paramaters based on higlights and shadows with a little bit more refinement but to be honest I’m not doing a lot of printing that it matters so much to me. My clients use pre-press houses for magazine and bill board ads that take care of that side of things. I would suggest trying several side by side and running your own printing tests similar to how I did here with your printer.

  5. Hello Karl, thank’s for these precious tips. And what about ICC profil ? Is it a good thing, when possible, to get it from labs and use it for proofing in Photoshop ?

    1. Hi Thierry, only if you have a top end calibrated monitor otherwise you aren’t going to see the difference. Most labs run and Srgb profile for printing to Inkjet or Theta through a RIP, profiling for CMYK though for printed books can be useful as the type of printing machine (Heidelberg etc) will have their own CMYK profiles. Different materials such as Ink Jet Rag, Acrylic dye bond etc will all have their own characteristics on how the final image looks but these are hard to accommodate on screen. I’d suggest test prints and keeping a library of them or samples from the printers your best bet to understand how something is going to look.
