Print Scanning

Your prints can be scanned using two different methods - bulk and manual scanning.  The one that is best for you can be determined by what your plans are for the final product.  If your goal is to simply archive copies of your prints, display them on a web-site or digital photo frame or make basic snapshot prints then bulk scanning is the most cost-effective method.  If you intend to make enlargement prints or are critical about the quality of the scan then manual scanning, although more expensive, is the better option.

Bulk Print Scanning

This is done with a high-speed, auto-feed scanner.  Your originals can be scanned at 300 or 600 optical PPI (pixels per inch).  No dust removal is performed by the bulk scanning process.  Enhancement (color and exposure) can optionally be performed on the whole batch scanned at no extra cost.  The scanned images are saved as JPG files.

Condition of originals:

·        Maximum width of the original cannot exceed 8 ½ inches.

·        Originals must be loose (not in albums or frames).

·        Originals must not be mounted to any kind of backing (mat board, fome-cor, cardboard).

·        Originals must be free of any sticky substances that would cause prints to stick together.

Originals that do not meet the above conditions will be manually scanned with the clients’ approval and necessary price adjustment.

Reasons to choose this method:

   * High speed (thousands of images can be scanned in a short period of time)
   * Low cost
   * Quick order completion

Things to be aware of with bulk print scanning:

·        Although uncommon, due to the speed at which the original is scanned artifacts can be introduced into the digital image by the scanner.  This most often appears as a streak or as a fine red, green or blue line that runs the length of the image.

·        Enhancement will not necessarily be applied adequately to all images.  Some incorrect colors or over/under exposure can occur.  You can opt to have enhancements done manually to a batch scan at additional cost.

Manual Print Scanning

Prints are scanned on a flat-bed scanner at 300, 600 or 1200 PPI.  Scan-time corrections can include:  sharpening, dust removal, color restoration and exposure correction.   Additional post-scanning edits can be done to further remove dust and restore color at additional charge.  In addition to JPG files, TIF files can be included too for a small extra charge per image.

Maximum size of the original cannot exceed 8 ½ x 12 inches.
Typical Digital Image Sizes from Print

The following table shows the approximate digital file size in megabytes and approximately how many can be stored on a CD or DVD based on a 4 x 6 inch original.

Resolution PPI           Bulk or Manual (JPG) -            Manual only (TIF) -
                                No. per CD / DVD                    No. per CD / DVD

300                           1.3 MB  -   450 / 3000             11.6 MB  -  50 / 330
600                           5.3 MB  -   100 / 740               46.7 MB  -  12 / 80
1200                         21 MB   -     25 / 180               187 MB   -    3 / 18


Slide / Negative Scanning

Slide / negative scanning is done at 1800, 2400, 3600 or 4800 PPI.  Digital ICE technology is used for reducing dust on color originals.  B&W originals can have dust removed manually at additional cost.  Additional post-scanning edits can be done to further remove dust, restore color and adjust exposure at additional charge.  In addition to JPG files, TIF files can be included too for a small extra charge per image.

Typical Digital Image Sizes from Slide / Negative

The table below shows the approximate digital file size in megabytes and approximately how many can be stored on a CD or DVD based on a 35mm color slide or negative.

Resolution PPI          JPG - No. per CD / DVD         TIF - No. per CD / DVD

1800                          4.4 MB  -  140 / 1000              23 MB  -   25 / 170
2400                          8.1 MB  -   70 / 540                 41 MB  -   14 / 90
3600                          17 MB   -   35 / 250                 92 MB  -    6 / 40
4800                          30 MB   -   19 / 140                162 MB -    3 / 20
