What is Print on Demand?

Print on Demand (PoD) is a business model where products are created only after an order is placed. At Subforma.com, this means that after ordering a product and uploading its design to the server, we proceed to print it specifically for you. There is no need to store ready-made products, which allows for greater flexibility in offering a wide range of designs. With PoD, you minimize costs related to storage and inventory management, and we guarantee that each wallpaper is freshly printed and delivered directly to your customer.

Design. It’s so simple and enjoyable

Preparing files for printing is simple and enjoyable when you know the basic rules. By using the right tools and guidelines, you can quickly and easily create files that meet all the printer's requirements. This makes the whole process easier and more satisfying, with the final result always meeting expectations.

How to prepare a file for printing

Preparing a file for printing is crucial to achieving the highest print quality. Below are the key guidelines to help you properly prepare your file:

File Format

Use the TIFF format
The file should be saved without layers
Apply LZW compression
Ensure the file does not contain an embedded color profile

File Size

Prepare the file at a 1:1 scale, meaning the actual size at which it will be printed.

Resolution

The file resolution should be between 80 to 300 dpi, depending on the final print size. Higher values are recommended for smaller prints to ensure the best quality.

Color Space

Work in the CMYK color space, which is the standard for printing.

Color Profile

Design the file using the Coated FOGRA39 profile to achieve accurate color reproduction in print.

Summary

Format: TIFF, no layers, LZW compression, no embedded profile.
Scale: 1:1.
Resolution: 80-300 dpi, depending on size.
Color Space: CMYK.
Profile: Coated FOGRA39.

Following these guidelines will ensure the highest quality and color accuracy in your prints. If you have additional questions or need assistance, contact our technical support team.

How to prepare a file using cut contour

Preparing a file for printing with cut contour may seem complicated, but with the right steps and tools, such as Adobe Illustrator, it can be done effectively. Below is the process for Cut Contours & Illustrator.

Creating a contour (Cut Contour)

Open Adobe Illustrator and load your design
Select the object you want to outline
Create a new layer named "Draw"
Use the Pen Tool (P) or another tool to draw the precise shape of your cut around the object
Make sure the contour is a closed path with a thickness of 0.099px

Defining the contour color

In the Swatches panel, create a new color swatch
Name the color "Draw" (exactly like this)
Set the color type to Spot Color
Select color #d88d2a
Go to "Attributes" and activate the "Overprint Stroke" option

Assigning the contour color

Select the drawn contour
In the Swatches panel, choose the previously created "Draw" color
Ensure that the contour is assigned as the cutting line

Checking correctness

Ensure that the contour (Draw) is correctly assigned and visible
Make sure the contour does not interfere with any other elements of the design
Verify that the contour is fully closed and accurately surrounds the object

Exporting the file

After completing the editing, save the file in AI or PDF format, according to the requirements. Ensure that the file is prepared in line with previous guidelines regarding format, resolution, color space, and color profile.

Summary

Creating the contour: Use the Pen Tool to draw a contour around the object
Defining the contour color: Create a new Spot Color named "Draw"
Assigning the contour color: Assign the "Draw" color to the contour
Checking correctness: Ensure the contour is correct and does not interfere with the design
Exporting the file: Save the file in the required format

Following these steps will ensure your project is ready for printing with precise cut contours. If you have further questions or need assistance, contact our technical support team.

Do I need to split the wallpaper file into panels before uploading?

No, that’s not necessary. The production file should be prepared as a single image, without panel division. Our professional RIP software automatically handles the paneling to ensure perfect pattern alignment and eliminate the risk of installation errors.

How should I prepare wallpaper files for printing?

The production file should be saved in TIFF format with LZW compression, using the CMYK color space and the Coated FOGRA39 color profile. The required resolution depends on the wallpaper size — for dimensions around 100x300 cm, we recommend 150–200 DPI. For larger formats, lower resolution is sufficient — for example, for 600x300 cm, 80–100 DPI is enough.

How should production files be named?

To maintain workflow clarity and avoid production errors, each production file should be named using the following format:

[OrderNumber]_[MaterialType]_[Size]

Example of a correctly named file:
216804404_ProwallSand_200x300cm.tif

Consistent file naming and a clear folder structure significantly streamline the printing process and order management.

How to Prepare a File for Wraps and Leaflets

To ensure the highest print quality and avoid technical issues, please prepare your file according to the following guidelines:

File format:
PDF (recommended) or TIFF/PNG (if you’re not using Adobe)
Color mode: CMYK
Resolution: 300 dpi
Scale: 1:1 (actual print size)

Bleeds:
Add 3 mm bleed on each side (the document should be larger than the final format)
Example: for a wrap (170 × 420 mm), the PDF should be sized 173 × 423 mm

Safe margin:
Place text and important elements at least 3–5 mm away from the trim line
Avoid placing logos, phone numbers, or QR codes too close to the edges

Fonts and text:
Convert all text to outlines (curves) or embed fonts in the PDF
This prevents display or conversion issues during printing

Colors and background:
Make sure your design is in CMYK color mode (not RGB)
Backgrounds should extend to the bleed — otherwise, a white edge may appear after trimming

How to Prepare a File for Packing Tape

File format:
PDF (recommended), alternatively AI, EPS, or TIFF
Vector versions are preferred (e.g. from Adobe Illustrator), especially if your design includes logos or text
The file should be created at a 1:1 scale — representing the actual size of one repeating section of the tape

Design size:
Design width = tape width: 48 mm
Length = length of one repeat pattern: 300 mm

Fonts and text:
Convert all text to outlines
Minimum text size is typically 6–8 pt, depending on the tape material and color

Background and margins:
Leave a 5 mm margin from the edges of the tape for important elements
If the background is printed — it should extend beyond the safe area
Backgrounds contrasting with the tape color (e.g. white print on brown kraft tape) should be solid and without transparency
