Nail Printer Gels Explained: Printing Gel, Base Gel, Cleaning Gel and Top Gel

1. Overview

The print quality of an AI nail printer is decided as much by its gels as by the machine. The system in this range uses four gels - a cleaning gel, a base gel, a printing gel and a top gel - shared across all nine printer models. This guide explains each gel's role, size and approximate yield.

2. The Four Gels at a Glance

3. The Three Printing Gel Finishes

The printing gel is the layer the inkjet design lands on, and its finish changes the result: PG0 is transparent for designs over the natural nail tone, PG4 is white for full-opacity colour work, and PG4+ is semi-transparent with a fine glitter effect. Salons typically stock all three; the base, cleaning and top gels are single standard items.

4. The Workflow the Gels Support

1. Prepare the nail with the cleaning gel step.
2. Apply the base gel, then the chosen printing gel.
3. Print the selected design with the nail printer.
4. Seal with the top gel.

Yield figures are catalog values: about 240-250 nails per 10 ml printing gel bottle and about 200 nails per 7 ml bottle of the other gels, varying with nail size and coverage.

5. Common Buyer Questions

Can I use any gel with a nail printer, or only the matched set?

The printing step needs a printing gel layer designed to receive the print. This range's workflow is specified around its own four-gel set, and results are only predictable with the matched consumables.

What is the difference between PG0, PG4+ and PG4 printing gels?

They are the three printing gel finishes in the catalog: PG0 is transparent, PG4+ is semi-transparent with fine glitter, and PG4 is white. All come in 10 ml bottles at about 240-250 nails per bottle.

Do gel consumables face import rules as cosmetics?

In many markets, nail gels are regulated as cosmetic products, and rules on ingredients differ by market. Importers should request the ingredient and safety documentation for the specific gels and confirm their local requirements before ordering.

6. A Note on Gel Ingredients and Market Rules

Gel ingredients are an active regulatory topic: for example, the European Union restricts certain photoinitiator ingredients used in gel products, including the substance known as TPO, and other markets review gel formulations against their own cosmetics rules. The practical step for importers is documentation, not assumptions: request the ingredient list and safety data for the exact gels you plan to import, and have your customs broker or regulator confirm them against your market's current rules before the first bulk order. Simiai Technology provides compliance documentation on request as part of the RFQ process.

7. Conclusion

Stock the gels as a set, not as separate experiments: one cleaning gel, one base gel, three printing gel finishes and one top gel cover every model in the range. See the consumables page for the cartridges that pair with them.
