TECHNICAL EVIDENCE

Checks that matter.

PRINTCHECK translates file properties into production decisions. Every warning includes a practical consequence and a clear next step.

Effective resolution

Calculates real DPI at the requested print size instead of trusting file metadata.

PX → MM → DPI

Transparency

Finds alpha-channel problems and semi-transparent edges that can affect the white base.

ALPHA CHECK

Canvas & margins

Compares the canvas with the actual artwork and flags excessive empty space.

BOUNDING BOX

Detached pixels

Detects small isolated components outside the main artwork before they reach film.

ISLAND ANALYSIS

Thin elements

Highlights details that may be too fine for reliable printing and application.

DETAIL RISK

Production verdict

Combines all checks into a readable pass, review or warning result for the operator.

PASS / REVIEW / WARN

FROM ARTWORK TO PRODUCTION

One controlled workflow.

Inspect the source, understand the risk, create a working copy when needed, then produce a clear approval or job card.

01

Preflight

Load PNG or JPG artwork, enter the target size and run the checks.

02

Understand

See what the problem means in production and how to verify it.

03

Repair copy

Work non-destructively: remove a uniform background, clean islands or resample a copy.

04

Document

Export a customer approval sheet or a production card as PDF or PNG.

REAL APPLICATION SCREENS

Built for the operator.

No staged mockups. These screens show the actual v0.4.2 desktop workflow.

LOCAL PROCESSING

Artwork stays on this device.

PRINTCHECK processes artwork locally. It does not use advertising, analytics, tracking, telemetry or cloud processing.

WHAT’S NEW

What’s new in 0.4.2

This release expands PRINTCHECK from file checking into a more complete pre-production workflow.

01

Non-destructive Repair copy

Crop transparent margins, remove detached islands or an edge-connected background, refine alpha and resample a working copy without overwriting the source.

02

Recheck and white-base preview

Run preflight again after a repair and preview a simulated white base before returning to production.

03

Stronger detail evidence

More precise evidence for thin and micro-sized elements helps the operator inspect genuinely risky areas.

04

More print placements

Custom placement plus left- and right-sleeve positions can be stored with jobs and included in backups.

05

Clearer production documents

Approval sheets and production cards carry placement, contact data, artwork facts and unresolved production risks more clearly.

06

Microsoft Store edition

The signed full edition is now available in Microsoft Store without a separate key. Artwork, jobs and settings remain local.

Before your first check.

The practical questions, answered.

Is PRINTCHECK really free?

Yes. PRINTCHECK is a private hobby project and is free to use. Supporting its development is optional and does not unlock extra features.

Do I need to install anything?

The quick check runs in your browser. For repair copies, saved jobs and production documents, use the Windows 10/11 app from Microsoft Store.

Which artwork files can I check?

PNG and JPG. Enter the intended print size so the resolution can be assessed at the size you will actually print. Use PNG when the artwork needs transparency.

Does a good result guarantee a good print?

A check helps you assess the file. It cannot predict every printer, ink, material or press setting. Review the warnings and make a test print when needed.

Does the Windows app upload my artwork?

The Windows app processes artwork locally on your computer. Exports are created when you request them. The app privacy policy explains the details.

Found a bug or have an idea?

I am Łukasz, the person building PRINTCHECK in my spare time. Tell me what happened and how to reproduce it.

Include the app version, your system, the steps and a screenshot of the problem. This helps me investigate.

Is PRINTCHECK making your work easier?

Built after hours and free to use. You can help me keep improving it.
