Q : What is bleed?
A : Bleed is a printing term and one of the prepress operations. Because there may be slight variations in the layout from the first page to the last page of a publication, to avoid the printed product being cut off or leaving a white border, in the design process, the production content (background, color) is usually extended beyond the actual page size. Bleed usually extends 3mm beyond the actual size of the printed item in all directions because the cutting process may not necessarily be precise with the actual size, so bleed must be reserved for cutting.

Q : What is converting text to outlines?
A : Due to font licensing issues, to avoid printing errors caused by different glyphs, please convert text to outlines (curves). After converting text to outlines, the original font becomes an object, allowing the same text design to be displayed on different computers.
Q : Color mode of image files: CMYK and RGB
A : The color mode of the web is RGB, and the color mode of printing is CMYK. Therefore, color differences will inevitably occur during printing. For good printing quality, please provide files in CMYK output mode to minimize color differences.
Q : Can the same color be displayed on different materials such as screens and photos ?
A : The same color cannot be displayed the same on different materials such as screens and photos! The color effects displayed on computer screens, inkjet drafts, photos, and large-scale printed paper will all be different, so they cannot be used as a reference for printing colors. For illustrations, please use actual printed products as a reference. Web color display is for reference only.
Q : Will the color change after lamination ?
A : After lamination, stickers, labels, and printed products are already processed, so the color after lamination cannot be predicted during printing, and even sample printing cannot achieve zero color difference.
Q : Will the color be the same in different print runs of the same file ?
A : In different print runs of the same file, there may be slight color differences due to density, temperature, and other issues. A color difference of about 3% from the sample is considered normal.
