When we work with clients on print design projects, we often get asked for advice on the technical aspects of printing. How long will it take to print Chinese New Year red packets? How do certain special effects or other requests impact the total costs? What is the difference between lamination and varnishing? Can the turnaround time be sped up?
First, let us address the most common question: what is the minimum high-resolution photo size for high quality printing across various media?
- For A4 sized brochures (full bleed photo), please provide photos that are 300dpi/150 MB
- For A1 sized posters (full bleed photo), photos for offset printing should ideally be 300dpi/400MB (150 dpi/100 MB if it is for inkjet printing)
- For exhibition booth walls (2m x 3m), photos are usually printed using inkjet printing, so please provide photos that are at least 150 dpi/150 MB
- For typical billboards (12m x3m), photos can be 100 dpi/150 MB (on inkjet)
But does dpi stand for? Next, we provide the explanations for common print production terms in relatively non-technical terms.
