Overprint varnishes

Protect the
print.
Define the final
appearance.

Varnish guidance for sheet-fed offset, metal decorating, flexographic and rotogravure printing. Start with your printing method, substrate, finished package and required performance.

Finish and protection reference

One varnish category, four
distinct printing routes.

Printing method first

Offset, metal, flexographic or rotogravure.

Finish with purpose

Gloss, matt and application-specific protection.

Production compatibility

Application, drying, curing and converting reviewed together.

Choose by printing method

How do you apply the
print?

Select the production route first. This prevents paper, metal and flexible-packaging varnishes from being treated as interchangeable products.

01

Sheet-Fed Offset

For commercial print, folding cartons, paper labels and suitable coated or uncoated paperboard.

02

Metal Printing

For decorated tinplate, aluminium, can bodies, decorative tins, caps and formed components.

03

Flexographic Printing

For labels, paper, board, corrugated and selected flexible-packaging applications.

04

Rotogravure Printing

For suitable flexible films, sleeves, labels and converted packaging structures.

Not sure which route applies?

Share the printed sample, substrate and equipment information available to you.

Process-specific varnish families

Separate routes. Clearer
selection.

Public categories explain the correct starting point. Final suitability is confirmed against the actual production system and trial conditions.

Metal printing

Varnish that
continues through
fabrication.

Metal varnish selection must consider the decorated surface, oven route, forming, seaming, handling and finished package—not appearance alone.

Gloss & matt varnishes

For controlled final appearance on suitable printed metal.

Heat & fabrication performance

Reviewed against curing, forming and component production.

Scratch & handling protection

For line movement, assembly, transport and finished use.

Application-specific resistance

Discussed against actual exposure and package requirements.

Paper, labels & flexible packaging

The print process
changes the
varnish route.

Sheet-fed offset, flexographic and rotogravure work use different substrates, application systems, drying conditions and converting demands.

Sheet-Fed Offset

For suitable paper, paperboard, labels and folding cartons.

• Oil-based overprint varnishes

• Water-based aqueous varnishes

• UV-curable varnishes

• Gloss, matt and protective finishes

Flexographic

For suitable labels, paper, board and selected packaging structures.

• Water-based varnish routes

• UV/LED-curable routes

• Solvent-based systems where applicable

• Handling and converting protection

Rotogravure

For suitable film, sleeve, label and converted packaging applications.

• Surface-print protective varnishes

• Gloss and matt finish routes

• Rub and exposure requirements

• Converting-related performance

Need Guidance

Share the package, substrate and production details you currently know.

• Printed sample or reference

• Application and drying system

• Final converting process

• Required appearance and protection

Choose by required result

What should the varnish
deliver?

The same finish name can require a different varnish route depending on the printing method, substrate and downstream process.

High gloss

For a bright, reflective final appearance where suitable.

Controlled matt finish

For a premium low-sheen surface matched to the application.

Scratch & rub resistance

For handling, transport and finished-package protection.

Heat resistance

Reviewed with drying, curing and downstream exposure.

Chemical or product resistance

Assessed against the actual contents and use conditions.

Converting compatibility

For folding, gluing, sealing, lamination, forming or fabrication.

Fast production response

Discussed around press speed and available drying capacity.

Surface protection

For controlled handling performance and print protection.

Need guidance

Start with the sample, line and performance problem.

Selection guidance

The complete production
route matters.

Provide the information available to you. Detailed product mapping follows the confirmed printing and converting requirement.

01

Printing method

Sheet-fed offset, metal printing, flexographic or rotogravure.

02

Substrate & ink

Paper, board, tinplate, aluminium, label stock or film plus the ink system.

03

Application route

Coating unit, roller, anilox or other available application details.

04

Drying & curing

Oxidative, hot air, IR, UV, LED or oven conditions.

05

Converting & fabrication

Folding, gluing, sealing, lamination, forming, seaming or assembly.

06

Reference & target

Existing varnish, printed sample, required finish or current problem.

Technical detail follows application review.

Product codes, formulations, detailed technical parameters, supplier information, documentation and commercial conditions are not published openly. They are provided as appropriate after the printing application is reviewed.
