Using Photoshop to make a test strip

Test strips are a useful way of testing your image before you print a full size version.

When making a test strip there are a few considerations:

  • If you are testing for a large print (30 x 20 inches and above) then you should produce a test at size – prints tend to ‘open up’ when you print larger showing more detail in darker tones and shadows.
  • You may wish to produce a test that has sections of various images on one print – these should also be done at size.


  1. First open the file you want to use for a test strip. The file will need to be at full size so that your strip is an accurate representation of the final print. If you are not sure how to do this, first go to sizing your image file in Photoshop.
  2. Select crop tool
  3. Input the dimensions and resolution for the crop required (please see our price list for test strip sizes). Our resolutions are:
    Up to 30 x 20 inches Larger than 30 x 20 inches
    C types 200 dpi 200 dpi
    Giclee 300 dpi
    Inkjet 300 dpi
  4. Drag the crop tool on the image to define area of test strip. Ideally you want to be selecting a crop that will include the broadest tonal range of your image (essentially both the brightest and darkest tones) and any important colours or details.
  5. Execute crop by clicking the green tick on your toolbar
  6. Save as and upload to Metroprint
