Are you not sure how you should prepare the artwork when you have art book printing in China? As a professional and international book printer, Image PPM offers simple but efficient guidelines (or standards) as below grids for your reference, which include general layout, color setting, font problem, image requirement, OPI and ICC etc. We believe you can get the artwork easily when you follow these standards. Please also do free feel to contact us for further assistant if you still have any problems.
