Object to Be Printed On

IMPORTANT

In this manual, the printed matter is called "object to be printed on," "object," or "media."

The UV ink used in this machine is an ink that instantly adheres to the object to be printed on by irradiating it with ultraviolet light. This makes it possible to perform printing on objects that are difficult to print on using conventional inks.

This section explains the materials and forms of objects to be printed on using the machine.

Even materials with the same name have many variations with different properties depending on slight differences in ingredients. Even if the ingredients are the same, printing may or may not be possible depending on differences in surface treatment such as plating or coating.

Even if a material is listed as a printable material, always be sure to perform a test print to confirm that satisfactory print quality can be achieved.

Objects that cannot be printed on or have print quality issues

  • In the case of objects that easily reflect light, the reflection of UV light may accelerate the curing of the UV ink on the surface of the print heads, resulting in ink discharge failure.
  • Objects to be printed on that are electrostatically charged should be discharged before use.

    If the ink is electrostatically charged, the position of the ink landing will not be stable, and printing quality will be adversely affected.

  • Objects with excessive unevenness cannot be used for printing.
  • If the object to be printed on still comes loose even with the flat table negative pressure activated, use commercially available tape or some other means to hold the object in place.

    If the object to be printed on comes loose, the ink emission surface of the print heads and the print surface can rub together, resulting in malfunction.

Conditions for Settable Objects to Be Printed on

The conditions for objects to be printed on that can be set in the machine are shown below.

Maximum size Width 2,440 mm (96 in.)
Length 1,220 mm (48 in.)
Thickness 95 mm (3.74 in.)
Maximum weight 45 kg/m2 (99 lb./m2)
IMPORTANT
  • Objects to be printed on that carry an electrical charge may cause ink discharge problems or decrease printing quality.
  • This printer cannot print on all materials. When selecting the object to be printed on, be sure to carry out testing in advance to make sure that satisfactory print quality can be obtained.
  • The variation in the unevenness on the print surface needs to be within 1 mm (39.37 mil). Variation larger than 1 mm (39.37 mil) may decrease printing quality.
  • Depending on the type of object to print on and the installation method, the height may not be set correctly. The machine may malfunction if printing is performed when an incorrect installation method is used or if printing is performed on an inappropriate material. Be careful when setting objects to be printed on that match the status or material shown below.

    Objects that easily become loose:

    If the object to be printed on is not firmly held in place, the height cannot be detected correctly. Be sure to set the object to be printed on firmly in place. If the media becomes loose, you can use a substance such as commercially available adhesive tape to hold the media in place.

    Objects made from soft material:

    The correct print head height cannot be automatically detected when printing on soft objects. In such cases, set the print head height manually.Setting the Print Head Height Manually
