What is UV inkjet printing?

Acrylic key chains and can badges - Full color from 1 piece - Printed in!
uvinkjet

UV inkjet printing is a printing system that uses a direct inkjet printer and irradiation of ultraviolet light to cure and fix the print.
It is characterized by its ability to print vividly and colorfully, enabling beautiful printing of original characters, logos, photos, etc., and the production of high-quality acrylic key rings with a good finish.
The quick drying process also allows for quick delivery.

About the expression of color in inkjet prints
Color reproduction in CYMK
Inkjet printing applies ink to the product, so the color will vary depending on the color of the product.
For color products, white ink, called "shirohiki" is sprayed on the base layer to improve the color rendering, and then each color is sprayed on top of it.
Inkjet printers use CMYK (C (Cyan) M (Magenta) Y (Yellow) K (Black)) and white ink for the base color.

On the other hand, TVs and computer monitors are expressed in RGB (R (Red), G (Green), and B (Blue)), Color differences may occur between the design on the monitor and the actual printed design.

Difference between CMYK and RGB color

Please note that the printed colors may appear darker or lighter due to the use of color cross printing.
Even if the design appears to have been created on the monitor in the same color as the fabric (e.g., black background on black fabric),
Printing on actual fabrics cannot be reproduced exactly as on the monitor due to differences in the color of your monitor, the texture of the fabric and ink, and other factors.
This is due to the nature of printing, so please understand and agree to this before ordering.

Precautions for data submission
uvinkjet
Gradient and translucent processing
Up-T uses white primer when printing on products in colors other than white.
Please note that designs with image blurring process (color adjustment with transparency including gradients and drop shadows) will be printed whitish due to the white of the priming material.
uvinkjet
Resolution and recommended size of data to be submitted
Please send the data for submission at a resolution of 300 dpi/inch. Smaller image sizes will not print cleanly.
Also, please note that the color of data taken with a digital camera will vary greatly depending on the model of digital camera and printer you have.

Don't forget to remove the background.
Please remove the background carefully and finely, as even a small amount of data with non-zero density (even if it was almost transparent) may cause the processor to react and print, resulting in a finished product that is not as desired. *Please note that a black background on a black item will be printed.

About line thickness
Textile items: 1Pt (0.35mm), non-fiber items: less than 2pt
lines are more difficult to print (and likely to be unprintable).

Be sure to delete unnecessary data.
Even if there is data in the submitted data (that you do not really want to print), we cannot determine whether the data is necessary or not, so the data will be printed as it is in the submitted data.
uvinkjet
Special colors cannot be printed.
Because full-color prints can be expressed in CMYK, special colors such as gold, silver, and fluorescent colors cannot be printed.

Other
Due to the nature of UV inkjet printing, depending on the humidity and temperature (especially high temperature and humidity) during shipping,
In rare cases, the printed surface may be stuck to the backing paper or vinyl bag.
If this is the case, peel it off slowly without pulling or flipping it hard.
When a part of the backing paper is left behind when peeling off, it can be removed without affecting the printed surface by wetting it with water and wiping it once.
