As a surface pattern designer I have historically used Adobe photoshop to create stand-alone repeating patterns with or without backgrounds that are also designed to incorporate texture and/or pattern. The resulting designs were saved as "defined patterns" and applied to artboards of any size using the following steps:
Open new document e.g. 10,000x10,000px
edit—-fill—-contents (select pattern option as opposed to foreground or background fill) ——select required pattern from a list—-ok
While I am very happy at the switch to Affinity I am struggling to figure out how to visually proof my designs this way (which are often designed using 2000px square artboards to create the repeat) when I need to be able to show that the repeat is working and simultaneously put the size it was created at into perspective. Also, some websites require large areas of repeat (up to 15,000px square) to enable on demand printing of fabric in the specific design.
I have attached a couple of examples below to demonstrate the kind of work that I am discussing here.
As a designer who is relatively new to digital systems I am focused on the creative aspect of my work and not especially tech savvy, so would appreciate an “idiots guide” approach to this if anyone has the time to respond. Any support with this would be much appreciated.
