A lesser-known kind of test pattern is used for the calibration of [[photocopier]]s.<ref>{{cite web|url=http://www.pcstats.com/articleview.cfm?articleid=1339&page=4 |title=Samsung SF531P PCSTATS Review – Printer Test Patterns |publisher=Pcstats.com |date=2007-10-15 |access-date=2010-01-01}}</ref><ref>{{cite web|url=http://www.thing.net/~grist/cyano/jangva/roomecho.htm |title=Projection: Room A / Room B |publisher=Thing.net |access-date=2010-01-01}}</ref> Photocopier test patterns are physical sheets that are photocopied, with the difference in the resulting photocopy revealing any tell-tale deviations or defects in the machine's ability to copy.

There are also test patterns kits and software developed specifically for many consumer electronics. The B&K Television Analyst was developed in the 1960s for testing monochrome TV sets in the NTSC standard and was later modified for European and Australian PAL standards. Among other uses, it consisted of a flying spot scanner on which a test pattern printed on a cellulose acetate slide was shown.<ref>{{cite web | url=https://www.cool386.com/b&k_1076/b&k1076.html | title=B&K 1076 Television Analyst }}</ref>

When [[Cathode-ray tube|CRT monitor]]s were still commonly used on [[personal computer]]s, specific test patterns were created for proper calibration of such monitors in the cases whereby multimedia images could not be shown properly on said monitors.<ref>{{cite web|url=https://underground-history.co.uk/tests/index.html |title=Monitor Settings Test |publisher=Underground History |date=2003-05-16 |access-date=2022-08-09}}</ref> Some [[Video CD|VCD]] and [[DVD]] lens cleaner discs, such as the [http://www.kyowasonic.com Kyowa Sonic] lens cleaning kits from 1997–2001, also included test patterns as well.<ref>{{cite web|url=https://www.youtube.com/watch?v=mrLBrz_7dVA&list=PLzhFkX1U-Ec3rS6goiN17_zbffA4t4Ejp |title=Lens Cleaner VCD |publisher=YouTube |date=2021-02-27 |access-date=2022-08-09}}</ref>
