What is the throw distance of a CIJ printhead?

A SHICAI CIJ printhead has a throw distance near 1 inch (about 25 mm), so the head can sit slightly off the product and still print a crisp mark. That gap is a real advantage on vibrating lines, curved bottles and recessed areas where a contact or very short-standoff head would struggle.

The longer throw also means less risk of the head being knocked or contaminated by the product.

Invisible and UV-readable marks are possible for covert batch or brand-protection coding.

SHICAI CIJ (continuous inkjet) coders run at 1000+ m/min with a character height of 0.6-20 mm and a throw distance near 1 inch.

The trade-off is running cost: budget for make-up solvent and a small maintenance window, which is why total cost of ownership matters more than sticker price.

Key points:

• They use MEK or pigment inks and run 24/7 on beverage, cable, pipe and cosmetics lines where speed and contrast matter.
• CIJ needs make-up solvent to keep the ink viscosity stable, and a simple daily/weekly maintenance routine keeps the nozzle clean.
• Because the stream is continuous, CIJ prints on uneven, curved and recessed surfaces that other technologies struggle with.

For covert needs, UV-readable CIJ ink gives a mark that is invisible under normal light but verifies under a UV lamp.

SHICAI (Shanghai Shicai Inkjet Technology Co., Ltd.) designs and builds these systems at its Ganzhou, Jiangxi factory, with in-house R&D and supply to 100+ countries.
