When requesting a high quality scan, what do I need to tell you?
- How you plan on using the digital image, that is, where and how will it be reproduced or displayed? Here are some possibilities:
- Offset Printing
- Inkjet or Laser Printer
- Film Recorder
- Website
- Data Projection
- What kind of original you'll be giving us, such as:
- Slide
- Transparency
- Negative
- Photograph
- Artwork
- Image or figure from a book or periodical
- What size your original is and at what size will it be reproduced, for example:
- 35mm slide to be scanned and placed into a PowerPoint Presentation
- 4x5” negative to be scanned and printed at 16x20” on an inkjet printer
- 8x10” photograph to be scanned and printed at 11x14 on an offset press
- What file format (e.g. tiff, jpeg) you would like your files saved in, and how you would like to receive your files from us (CD, DVD, e-mail, or FTP transfer)?
Why should I have you do my scans when I have my own desktop scanner?
Our expertise gives you the results you need…
When converting any image from analog to digital, information can be permanently lost or added to the file. This results in altered color, density, and contrast of the image. Our expert digital imaging specialists have the ability to optimize the digital capture of your original; we can match the original color, density, and contrast, and in some cases actually improve the image through post processing and manipulation. We have the ability to enhance and preserve highlight and shadow detail of the original, and maintain color fidelity throughout our color-managed workflow, from capture to print.
We take the guesswork out of the process…
Certain output requires much higher capture resolution than consumer scanners are capable of optically. When you scan at a different resolution than required, the software adds or subtracts pixels to give you a correct file size. The software does this by simply guessing what those pixels should be, through a process called interpolation. We can determine the exact resolution at which to capture, eliminating the need for software interpolation.
What are some of the benefits?
-
Image quality: high spatial and color resolution good enough for almost any application including traditional offset printing; good dynamic range including shadow and highlight detail, color fidelity and low noise levels
- Our expertise in scanning various types of originals for specific applications
- Our ability to improve or optimize images through post processing or manipulation
- Time. We can save you time when you have dozens or hundreds of originals that need to be digitized.
Here's a list of our output devices with a description of our resolution requirements for each.
Large Format - 200ppi and no greater than 300ppi for each inch at the size you would like us to print it.
Archival, exhibition - 300ppi at final size
*Note the maximum size for output on our archival printer is 17” x any length to 100', and can be printed with or without borders.
B & W Tabloid Size - 400ppi at final size
*Note that the maximum size for output on this printer is tabloid (11" x 17") including margins.
Film recorder - For output to our film recorder we recommend images that are 4"x6" at 300ppi and saved as a TIFF or EPS files. Your images should be oriented to make the best use of the frame on your slides. Standard 35mm slide film allows for an image aspect ratio of 2 x 3 units.
