I coded a quick web app for a particular book arts need: Limited Letterpress Synonym Finder. If you too also only have 1xA-Z letterpress type on hand (ie just the 26 characters of the alphabet, 1 sort per letter), you can enter words here to see only those synonyms you’re able to print (i.e. only synonyms using no more than 1 of each A-Z letter).

Screenshot of the Limited Letterpress Synonym Finder webpage linked in the post, which says "Limited Letterpress Synonym Finder. For when you only have 1 x A-Z type on hand. Finds synonyms for the word you input, removes any that use any letter more than once, then displays the rest. (Only works with single-word inputs, not phrases.)" There is a field to enter words, with the word "glow" entered in this example screenshot, followed by a "Find that subset of synonyms" button. There is a list of matching non-multiple-same-letter synonyms for "glow" shown, containing the words burn, beam, shine, gleam, and lambency. Below is a retro internet logo image: on a black background, the text "Limited Letterpress: Synonym Finder" is in a glowing green neon Old English font.
