Differences between the two processes determine the method to be used in certain printing jobs. The important factor to consider is the price based on quantity and time. The strengths of offset printing are image resolution, reproduction speed, paper selection, and the declining cost per image as the print run lengthens [Suggestion: Insert link to offset printing definition]. It is highly recommended for projects requiring 500 pcs. or more; images with fine lines, photographs, screens or tints; and when using a thick or coated stock.
The strengths of digital printing are the following: once the image is at the printer, nothing more is required to produce the first print; the sheets can be handled, folded, cut or padded immediately after being printed; and an RGB color image can be printed. It is recommended for rush printing projects, especially if bindery operations (such as folding, cutting or padding) are required immediately; and only a few copies of the print is needed.
Here are more points to consider:- Quantity. Offset printing has a front-end cost load. Short runs may have a high unit cost. But as quantities increase, the unit cost goes down with offset printing. Very short runs can be much more cost effective with digital printing; while larger quantities are likely to have a lower unit cost with offset printing.
- Printing medium. Offset printing still offers the most flexibility for special paper, finish, uncommon printing surface or unique size.
- Color. If you need only black ink or one or two ink colors, offset printing may offer a more cost-effective solution. If you need four-color printing, digital may offer advantages in lower up-front costs.
- Turnaround. If you need it fast, digital usually offers quicker delivery.
- Proofing. Digital offers accurate proofs since you see an actual sample of the printed piece. Accurate color proofing for offset printing can be expensive.
- Customization. Digital printing offers the most affordable way to customize marketing materials, direct mail pieces, letters, etc.
