One question small and mid-sized printers often ask is â€œwhat do I about scanning?â€
Deciding how your shop will manage and offer scanning services can be confusing. There are so many choices and types of scanners that researching scanners can be overwhelming. The scanner and the services associated with it can be an important part of the printing services offered, so it is paramount that printers be armed with information to help them in their choice of a scanner. Is it worth investing money in an expensive scanner, or will an inexpensive scanner perform just as well?
With all the advances in desktop technology, nobody seems to talk very much about scanning. One reason is that a printerâ€™s customers now do much more of their own scanning and rely on printers to do it less.
Cost of any equipment is always a primary concern to printers. For purposes of this discussion and the type of work to be performed, it is best to break scanner costs into three categories, low-end, medium quality, and high-end.
The first category is low-end desktop flatbed scanners, which means using low-cost consumer flatbed scanners. These are flatbed scanners and can be as inexpensive as $50, but are typically no higher than $1,800, with the average price being somewhere between $300 and $1200.
These scanners can be bought at a Staples of through a company like PC Connection.
Typical names of manufacturers are Epson, Umax, Microtech, and others.
These scanners are good for lower quality jobs. And while it is possible that someone who is really good at color and has some time to spend, may get a good reflective scan out of it, the quality will be too low for most printers. These scanners work best on reflective art, but should not be used to attempt high-quality transparency scans.
They tend to fail in several areas: they donâ€™t capture detail in shadow areas, the general quality of the first scan is poor, and there are occasional optical defects. If this is the only scanner in your price range there are some things it can do well. Many of these can do decent monochrome halftone scans. They also can be used for low-quality color scanning, but I would be wary of attempting quality color scanning with these scanners.
The second category is medium quality, which means using professional quality flatbed scanners. These are flatbed scanners and range in price from $2,500 to $40,000. These scanners include better mechanical components and electronics than the less expensive consumer flatbeds. They also contain better CCD diodes and light sources than the less expensive devices, as well as software that helps check things such as light intensity and calibration. These scanners are typically sold by graphic arts dealers and manufacturers such as your local dealer or directly through a manufacturer.
manufacturers in this category include Creo,
For professional results, prepare to spend in the $10,000 to $40,000 price range. In general, these scanners still can have some issues with detail in shadow areas, although they are used for high-quality commercial production on a regular basis.
The third category is the
high-quality drum scanning. There is a good reason that everyone else keeps
comparing their scanners to drum scanners, and thatâ€™s because the quality is
the best that can be achieved. With that being said, you see fewer and fewer
drum scanners today. These can be purchased from dealers and manufacturers.
Drum scanners are made by manufacturers such as
With that being said,
drum scanners are used less and less, probably because of cost and difficulty
of operation. As with the previous category, a lot of the manufacturers have
left the market â€” such as
Changes in the Scanner World
The thinning out
of the marketplace has become a serious issue. Nowhere is the more noticeable
than in the selling of drum scanners. Companies such as Optronics, Howtech, and
In the past printers knew where to go, who to talk to, and how much it would cost. Evaluating scanners today is made more complicated by the numerous choices, and lack of training and product support provided by manufacturers.
Once a printer owns the equipment, installation, training, and maintenance often falls to him rather than an external support organization.
Staff is important too
The scanner isnâ€™t the only part of the scanning equation. It is important to remember that the operator in many cases can be as important a factor as the choice of the actual scanner itself.
For example, good scanner operators can provide decent scans from mediocre scanners, and poor scanner operators may be unable to provide decent scans from professional scanners. It is important to think of who will run the scanner, and the types of skills and experience that they have.
You cannot expect the average prepress operator to automatically produce professional quality scans unless they have had experience or training. Keep in mind that the scanner is one part of the equation, but staff plays an important part in your capabilities.
How do you know which is appropriate? Think of the quality of the work you are producing, and also think about what your customers are giving you. There is a lot of work that does not require high-quality scanning. If your customer will accept that work you may be off the hook regarding expensive scanners. Many small and mid-size printers only do low-cost, or medium-quality, and send out any really color critical scans to be done by professionals. If you attempt to do high-quality color scanning, not only do you need the equipment, you also need the staff. And professional scanner operators can be hard to find and are often well paid.
The scanner and the services associated with it can be an important part of the printing services offered, so the choice of a scanner is important. In general, unless all your work is low quality, it is worth investing in a decent scanner.
Tom Bakke of Tekgraf, Inc., whose company provides all three levels of scanners to the graphic arts dealers around the country and has worked with every major manufacturer over the years.
â€œWhen choosing a scanner look at the software first to make sure it has the latest features such as integrated International Color Consortium (ICC) workflow and good color correction ability,â€ Bakke said. â€œ Iâ€™d recommend if you are looking towards a professional grade scanner look to the companies that provide on-site training with the purchase of the scanner and good telephone support after the sale.
â€œMost scanner manufacturers will offer training at an additional cost which is fine, but there are some companies that offer on-site training with the purchase of the scanner,â€ Bakke said. â€œAlso, on-site warranty service is a must.â€ If you would like to ask questions of Tom Bakke you can reach him at firstname.lastname@example.org
