What This Video Shows

A full written description of the demonstration, so the content is readable without playing the video.

This video demonstrates SJH anti-counterfeit black ink: pure black, strong coverage and stable printing - a base colour for tickets, packaging and documents.

1. Blackness and hue

The video shows the printed blackness and hue of the anti-counterfeit black ink. Requirements for black are stricter than expected: a blue, brown or red cast affects how it combines with spot colours, and uniformity of blackness across large solid areas directly shapes how a document looks. Blackness and hue stability are therefore key specifications.

2. Coverage and solid printing

The camera shows coverage across large solid areas. Black must fully cover the base paper colour and background pattern; in barcode and machine-readable areas especially, the base showing through causes reading failures. Coverage relates to pigment concentration and film thickness, so ink volume and mesh should be fixed by proofing for solid work.

3. Printing stability

Finally the video shows performance under continuous printing. Black is the highest-volume base colour, and printing stability - no scumming, no ink piling, consistent drying - directly determines efficiency and reject rate. A press trial before volume use is recommended to confirm compatibility with your equipment and drying conditions.

Key Points

Hue	Pure blackness with no cast, to keep spot colour combinations and document consistency
Coverage	Fully covers base colour and pattern, critical in machine-readable areas
Production	Printing stability drives efficiency and reject rate - run a press trial before volume use
Typical use	Tickets, packaging, documents and barcode / machine-readable areas

Black looks like the most basic ink but is the highest-volume and most demanding in printing stability: a single batch problem affects far more print than any spot colour. Where barcodes, QR codes or machine-readable areas are involved, coverage must be validated by proofing, so that show-through does not cause whole-batch reading failure.

Frequently Asked Questions

Selection, detection, printing and ordering — answered.

Why does black ink actually demand the highest stability?

Because it is the highest-volume ink. A single batch problem affects far more print than any spot colour, so printing stability drives efficiency and reject rate directly. Black looks basic but is the real test of a supplier quality control.

Why is coverage a critical specification?

Because tickets, packaging and documents often carry barcodes, QR codes or machine-readable areas. Insufficient coverage lets the base colour or pattern show through, disturbing reading and in serious cases causing whole-batch reading failure. Coverage in machine-readable areas must be validated at proofing.

How can printing stability be ensured?

Run a press trial before volume use. A trial exposes real issues in ink behaviour, drying and overprint sequence far better than a test report alone, and markedly lowers the risk of scrapping a whole run - especially the first time a batch is used.

Why does hue neutrality matter?

Because black is often used alongside spot colours; a weak blackness or a blue or brown cast alters how the spot colours appear and breaks document consistency. Pure blackness with no cast is what makes the colour build reproducible.
