Wash Fastness and Color Bleeding of Hong-Jet^® Latex Printing

On textile fabrics, prints can withstand hand washing at room temperature with mild detergents and are not suitable for heavy-duty industrial washing. For leather, film materials and wall coverings, only rub resistance tests are carried out, and no washing tests are performed. After full curing (usually 10–30 minutes), minor water splashes and alcohol wiping will not cause color bleeding. It has a certain degree of water resistance but is not completely waterproof; color migration will occur after prolonged soaking.

Can I test JETALL^® latex ink on my existing UV printer?

It is not recommended. Most UV printers are equipped with i3200-U1 UV printheads. The internal sealing materials of the printheads are incompatible with water-based latex ink and will be corroded and damaged. Even for models with A1 water-based printheads, the complete ink supply, damper and curing system of UV printers do not match latex ink.

What is OP? How to Perform Digital Foil Stamping

OP refers to the supporting clear latex varnish, which can be printed on the same machine together with CMYK and white ink. It improves adhesion, adjusts glossiness, and acts as the key medium for digital foil stamping. Foil stamping procedure: Print OP on the stamping area → Lay foil while OP is not fully dried → Hot pressing → Peel off the base film to leave the golden pattern. No plate-making is required, and variable data is supported.

Can the Hong-Jet^® HJ-6090 Model Print on All Kinds of Genuine Leather?

No. Corrected grain leather, semi-aniline leather and aniline leather can be printed stably after testing. For top-grain leather with heavy oil and wax on the surface, grease will lead to poor adhesion, so degreasing pre-treatment is mandatory. We require customers to send genuine leather samples for laboratory adhesion testing before placing orders.

Can I Directly Switch to JETALL^® Latex Ink on My Existing Machine with i3200 Printheads?

Modification is only possible if your machine is originally fitted with i3200-A1 water-based printheads and a full water-based ink circulation system. If equipped with i3200-U1 UV printheads, ink replacement is strictly prohibited as it will cause immediate printhead damage. Even for A1 water-based printers: the entire ink circuit must be thoroughly cleaned, with supporting white ink circulation system and drying device installed. We do not support simple direct ink replacement. You may send equipment information and media samples to us to assess modification feasibility.
