Choose the type of Printing Support White

Backing white is an essential printing technique for ensuring color vibrancy on non-white or transparent substrates.
It acts as an opaque base that intensifies the colors printed over it.

But how do you choose between selective and full support white?

This article guides you through the pros and cons of each option, with concrete examples to help you make the best decision.

1. Blanc de soutien total: full coverage for maximum impact

Total white support involves applying a layer of white to the entire surface to be printed.

Advantages :

Vibrant colors: Ideal for dark or colored substrates, it ensures faithful reproduction of colors, preventing them from being attenuated by the color of the substrate.
Guaranteed opacity: Perfect for transparent substrates such as glass or plastic, it creates an opaque base that prevents light from passing through the print.
Uniformity: Ensures a uniform base for printing, which is particularly important for complex designs with gradients or fine details.

Examples of use:

Stickers and labels: for food or cosmetics labels on dark backgrounds, a full white backing ensures that the information and logo are clearly visible.
Interior signage: for directional signs in Plexiglas, full white support ensures vivid colors and excellent legibility.
Packaging: for luxury packaging on black cardboard, it ensures high-end rendering and optimal color perception.

2. Selective backing white: precision and elegance for a high-contrast finish

Selective white support is only applied to specific areas where colors need to be reinforced.

Advantages :

Contrast effect: creates interesting visual effects by playing with the transparency of the substrate.
Economy: reduces white ink consumption, which can be advantageous for large print runs.
Subtlety: ideal for designs requiring a touch of sophistication and discretion.

Examples of use:

Business cards: to highlight a logo or text on colored paper, while letting the texture of the paper shine through.
Flyers and brochures: create original graphic effects by combining areas printed in color with transparent areas.
Textile: for printing patterns on dark garments, maintaining a soft feel and avoiding a "plastic" effect.

How to choose?

The choice between total and selective white support depends on several factors:

Type of substrate: for dark or transparent substrates, full support white is generally preferable.
The desired effect: if you're looking for maximum impact and vibrant colors, opt for full support white. If you prefer a more subtle effect and a play of contrasts, selective support white is more appropriate.
The budget: Selective white back-up can be more economical for large print runs, as it reduces white ink consumption.

In short, backing white is a powerful tool for enhancing your prints.
