We cannot edit PDF files.
Some clients asked us to change language English into Japanese.
In this case we need have an original file such as Illustrator.
Please check bleed is enough.
No bleed we cannot trim, please do double check.
Stock is NOT same as your country.
Stock(paper) in Japan might be different with thickness, texture and the color.
Please be careful production time to avoid the rush charge.
Bleeds are very important for fine printing.
Please make sure there are bleeds on yours.
