Design Guide

How to prepare your files for hot foil stamping

To ensure a smooth and efficient production process, there are several key considerations required at the design stage, when preparing the artwork file and when placing the order.
This guide provides stamping tool manufacturers with all the necessary information, covering topics such as file format, layer setup, design limits, and order details.

Design Guide – how to prepare files for hot stamping and embossing tools

File formats — what is accepted

Most tool manufacturers can process common file formats for Mac and PC. Vector files are preferred, as they are scalable without quality loss and enable precise tool manufacturing.

Preferred

Adobe Illustrator

.ai or .eps — vector, scalable, no quality loss

Accepted

Adobe Acrobat

.pdf — widely supported, check embed settings

Accepted

Adobe Photoshop

.psd — minimum 1200 dpi bitmap resolution required

Accepted

Adobe InDesign

.indd — package file with all linked files included

Note: All fonts and strokes must be converted to paths — no live text elements in the final file. If unsure about the right format, please contact your tool manufacturer in advance.

Adobe Illustrator with label artwork open — vector files preferred

Adobe Illustrator with label artwork open — vector files (.ai, .eps) are the preferred format for hot stamping tool production

File specifications — the checklist

The requirements vary depending on the type of embellishment. The following applies to all common tool manufacturers and is valid for flat stamping, embossing, and combination jobs.

Requirements for all job types
All artwork sized at 100%
Remove all clipping masks
Convert all strokes and text to paths / outlines
Do not use compound paths
Do not apply line weight to paths
No intersecting lines
Indicate web direction / print side if no text is present
Save file with named layers (one layer per foil or embossing level)
Minimum resolution 1200 dpi (for bitmap files)
Additional requirements for embossing
Specify embossing style: round, flat or other
Indicate if crop or registration marks are required on the tool
Additional requirements for combination jobs
Clearly indicate which areas are flat stamping vs. embossing

Give layers the right name

Each foil and embossing level should have its own dedicated layer.
Using descriptive names for layers — rather than generic names like ‘Layer 1’ — saves time in tool design and avoids costly back-and-forth.

The optimal artwork file for labels includes:

The web direction
Artwork divided into separate layers
Layers named by function (e.g. silver foil, blind embossing)
Cut lines, frames or centre lines for positioning the drill pattern

Layer 01

Cutting / registration marks

Cut line and frame for positioning the pattern

Layer 02

Silver foil / gold foil…

Flat stamping, one layer per foil type and colour

Layer 03

Embossing / relief

Level 1, 2, 3 separately — never all on one layer

Correct: separate layers per function

Correct: separate layers per function

Incorrect: all artwork on one layer

Incorrect: all artwork on one layer

Design limits and minimum dimensions

The design limits always depend on the chosen embellishment type and the material used, and must stay within the tool manufacturer's specifications.
As a general guideline, the following minimum values apply:

No intersecting lines

If motif elements overlap in the design, the paths must be separated, with each element placed on its own layer. Lines that cross each other cannot be engraved correctly, resulting in tool defects. Therefore, always use filled shapes and ensure clean, non-overlapping paths.

Correct example: bow illustration drawn with clean, non-intersecting vector paths

Correct: paths do not intersect

Incorrect example: bow illustration with overlapping and intersecting vector paths

Incorrect: intersecting lines in artwork

Additional requirements
