How much bigger should the plate be than the image?

Add 5-10 mm on each side for handling and registration. Lino blocks need more margin (10 mm) for grip. Metal plates need less (5 mm). The extra area also protects the image edges during inking and printing.

What is a bevel and why do I need one?

A bevel is an angled edge filed on metal plates (copper, zinc). It prevents the sharp plate edge from cutting the paper or blankets during printing. Bevel width is typically 2-3 mm at 45 degrees on all four edges.

What thickness of metal plate should I use?

Copper plates are typically 1.0-1.2 mm thick for etching. Zinc plates are 1.6 mm. Thinner plates (0.8 mm) are cheaper but bend more easily. For dry point, use thicker plates to withstand the pressure of incising.

What are the alternatives to traditional metal plates?

Lino (3.2 mm) is the most common relief printing material. MDF and acrylic (3 mm) work for collagraph. Tetrapak and mounting board are excellent for beginners. Solar plates offer photographic etching without acid.

How do I cut metal plates to size?

Use a plate shear or heavy-duty guillotine for clean cuts. Mark the cutting line with a scribe. After cutting, file all edges and bevel them. Deburr thoroughly — sharp edges will damage blankets and paper.

How We Calculate This

How Plate Size Calculation Works

Plate = Image + Handling margin + Bevel allowance

The image dimensions are increased by a handling margin on each side (10 mm for lino, 5 mm for metal). The plate area, bevel length and estimated weight are calculated based on the material type and standard thicknesses.
