Here are some commonly asked questions regarding the printing and operations of RNJet printers :

What is the maximum print speed of the machines?

The RNJet H1+ can reach printing speeds of up to 180m/min.

Our large character printers can print up to 90m/min.

Our small character printers piezo can print at 60m/min.

how much set-up do the printers require?

Our printers are ready for use right out of the box. Installation and set-up could be done in 10-15 minutes (depends on the production line).

What type of content can the machines print?

With RNJet printers, customers can mark and code the following info on practically any surface:

  • variable data
  • lot/batch numbers
  • production dates
  • barcodes
  • shifts
  • logos and images
  • dynamic databases
  • dynamic barcodes such as Data Matrix
  • external info from barcode scanner, scales, etc
  • and much more


Are the printers capable of printing auto dates and counters?

Yes, all of our printers have this functionality.

Can i print at temperatures below freezing?

Oil gets thicker under zero degrees Celsius, resulting in diminished print quality.

Can dual head printers operate on two separate production lines?

Unfortunately, no. You can print with dual head printers on only one production line. The printer has only one photocell.

It is vital that every customer has access to clear information about the product they are consuming. From tracking & tracing to expiry dates, batch numbers, scannable QR codes & more, selecting the proper ink for your project ensures a consistent, clear print every time. 

Here are some commonly asked questions regarding ink selection and application :

What types of inks are available?

For TIJ , we offer solvent-based, water-based, UV and food-grade ink. For Piezo, we have oil, solvent-based, UV and food-grade ink available.

What color inks are available?

Solvent-Based inks are available in black, pigmented white, pigmented yellow, blue, orange, and red.

Oil-Based inks are available in black, red and blue.

Water-Based inks for TIJ are available in black, blue, and red.

Food-Grade ink is available in dark pink and blue.

UV ink is available in black and white.

What is the difference between oil and solvent-based inks?

Oil-based inks are odorless and offer the advantage of being more resistant to water and lighter than water-based inks.

Solvent-based inks are used as the carrier for the colorants. This solvent evaporates during printing. The advantage of these inks is that they adhere to a wide range of materials.

How many prints can i get from a single cartridge?

For Hi-Resolution Piezo Models while using a 2 mm font print height about 15 million characters can be printed per single cartridge. For TIJ Models you could roughly get 8.3 million characters (2mm height) per cartridge.

Can i purchase ink from other suppliers?

To ensure optimal performance of your RNJet Printer, we do not recommend purchasing ink from other suppliers, as they may not be compatible with our machines.

for tij printers could i switch ink from water-based to solvent-based or UV or food-grade?

Easily. RNJet TIJ printers (like RNJet H1+, RNJet H2+, RNJet EP-6H+) is based on cartridge-based thermal inkjet technology, that’s why to switch the colors or the type of the ink you will need just simply replace the cartridge. No any other cleaning or maintenance are required. 

can i switch from oil to solvent-based ink or vice-versa?

Unfortunately, this switch cannot be made because of incompatibility with the print engine.

Which ink type is most suitable for my application?

A few factors need to be considered when choosing the right ink for your production needs:

1) What kind of substrate will you be printing on? Is the material porous (cardboard, paper, non-finished wood), or non-porous (glass, metal, plastic).

2) What type of environment will the product be exposed to during its lifecycle? Take into account temperature range, humidity, presence of chemicals, etc.

3) How important is the ink’s drying time? Does your application require a fast dry ink?

4) What types of adhesion characteristics does the print require? Strong adhesion, durability, indelibility?
