Most design-related issues can be avoided with proper file setup. Here are the questions we get asked daily in China.

| Do you need fonts outlined? | Yes, or embed all fonts to avoid text changes during production in China. |
| Can I include variable data (names/addresses)? | Yes, Excel/CSV format accepted. Additional charge applies for digital variable printing in China. |
| Will my Pantone color be exact? | 100% match with Pantone spot ink; CMYK simulation has slight variation in China. |
