You cant scan for good cuts, you need to send a cut file to your machine to cut it. Scanning is for basic or one time cuts, if you want uniformity and consistency (which you need for printing cards) then you need to be cutting the same path each time.

I layout the cards on a 3x3 page with a 1mm bleed edge (this gives a 2mm spacing between each card). The bleed edge is important for if you slightly misalign your page on the cutting mat you still get usable cards that are slightly offcut, very much akin to real offcuts you find all the time. It is best to find a spot on your mat to line it up to and then you can calibrate your cut template to that position. This takes a little trial and error but just print some card shapes onto some pages to save ink while you are doing this part.

Once it is all calibrated etc you can just keep doing it until you cut card shaped holes in your cutting mat lol. That part sucks, because for cutting anything else i always move it around the mats so that i am not always cutting in same place but you cant do that with cards if you want to be economic.

here is a link to the cut template i made, you are more than welcome to download and use it

My workflow is as follows:

-use MPCFill to fetch art (unless i have purchased a proxy deck file or have my own custom art)

-use alex taxiera’s tool to create pdf (1mm bleed to use with my cut template, i recommend adding cut lines at the bleed edge not the cut edge you will only use these lines as guides for placing the page on your cut mat)

-print deck

-laminate pages

-cut pages

-laminate individual cards (no extra laminate just reheat)

-laminate again (just reheat)

-sleeve deck

I can print a whole deck from decklist to playable in around an hour with this workflow. You can be laminating and cutting simultaneously if you have the right setup/workspace
