Defining the Test Chart Layout

In the Finalize step, you see a preview of the test chart layout and can adjust it to your needs.

Finalize Test Chart window.

You can change the dimensions of the test chart (1). The number of color patches will be adjusted accordingly. You can add pages to include more patches if not all possible patches fit onto a single page (2).

If you create a test chart to be measured in scan mode, it is recommended to add black and white gaps in-between patch columns to make sure the measuring device will be able to recognize the patch borders correctly. If you create a test chart to be measured in manual mode, you can deactivate the gaps to save space (3).

Measuring a test chart without gaps in scan mode is possible in many cases. If you are unsure whether or not you will need gaps , you can make a measurement test run using a proofing paper before sending the test chart to the printing company.

GMG OpenColor uses a smart algorithm to fill the available space with color patches. It starts wit the most important (full tone) patches and adds patches in the order of priority. Also, dark and light patches are alternated. This way, it is often possible to use scan mode even when gaps are deactivated.

You can then export the created test chart as PDF and send it to your printer. You can then measure the printed test chart in GMG OpenColor to characterize the printing condition under it was printed.
