Artwork Dimensions
The working size is the size including the bleed which is different for each product. The work size is the same as the virtual artboard size. By downloading a printable template from the "Ordering Page > Template" for each product, you can check the exact size of each product.
Bleed Setup
Because of the nature of the printing process, if there is a background image, it is not easy to print perfectly to the end of the paper. The background image is therefore printed larger than the actual cut area, and cut to the right size. The printing process Bleed goes beyond the edge of the sheet to be cuts. Depending on the production facilities, Bleed sizes differ according to country, print shop and product. For the rest of the world, it normally is 2 ~ 5 mm. Please check the bleed size by product for each product page.
Order Set(s)/Array
The order sets indicate the amount of different designs for the same specification (size, material, quantity, etc.).
CMYK Color Mode
All of the files to be printed should use the CMYK color space. It is very important. The colors can't print as expected if the file is designed in the RGB colorspace.

Resolution
Have you ever looked like a mosaic or blurred image when you print an image that looks sharp on a smartphone?
This is a natural phenomenon due to insufficient image resolution. Printable image resolution is typically optimized at about 300 pixels per inch. If you are creating a 4x6 inch postcard, you should first check whether the data is 1200x1800 pixels. The lowest image resolution for standard print quality is 240 pixels per inch.

Opacity
If you give the document a transparency effect, you should flatten the object. Flattening separates artwork with transparent effects from vector-based regions and raster-based regions. Flattening is a necessary process for printing complex artwork, including mixed images, vector objects, fonts, spot colors, and overprinting. If flattening is not performed, the following results may occur.
- A white halo appears around the drop shadowed font.
- Printable PDF capacity increases.
- The photographic image is printed in brighter than the original color.
- Gradation effects are not rendered properly.
Adobe Illustrator
- Illustrations, and InDesign, and select "Acrobat 4.0 (PDF 1.3)" to save the PDF as flattening. Or from the illustration menu as shown below. Object > Flatten Transparency (Transparency merging) function.
Gradient / Mesh / Blend Objects
Gradient, mesh, and blend effects appear on the monitor, so if you want smooth printing without banding, you need to take into account variables such as final printing equipment, gradient step coverage, illustration, or using Photoshop. Please use the "Rasterize" function as below for the effects basically and contact the customer center for more information.

TIP. Use light colors or shorten dark blends. The banding occurs frequently in very dark colors and white colors.
Locked objects
Locked objects must be unlocked as shown below.
