Registering a two-color lino print involves accurately aligning the paper with the inked linoleum blocks for each color layer so that the colors print in the correct positions relative to each other.
Create a Registration Jig out of some spare lino for the printing blocks and make some card tabs using card and double side tape for registering the paper.
Thay are other ways to register your print but thiws worked for me on these small prints
Tip: When i have carved my block for first colour i use quick drying water based ink to print a proof. If it ok, I put a pre-carved second block into the Jig and place still wet print from previous block over new block and pass through press. Now i will have image on new block. Let is dry and carve next colour, wash off and both blocks should register perfectly.
