How to scan artwork

Introduction to scanning artwork

Autonomously from photographing artwork, scanning is another method for converting your fine art into digital images. Yous tin pay a scanning agency to scan your work with a drum scanner, simply yous tin often accomplish practiced quality results with a flatbed scanner at habitation.

Professional pulsate scanning

Generally, drum scanners are of an impressive size and correspondingly expensive, costing around as much as a car or a small-scale business firm. These are used by pro labs to scan your film, and so it is hardly surprising that a high-resolution scan can cost £25 to £50 a fourth dimension. The drums used are typically a metre or and so long, and a number of images are scanned at the aforementioned time, each negative being held on a pocket-size function of the pulsate's surface.

The light source is in the middle of the drum and the photocell outside. As the drum rotates, it scans every bespeak on a circumvolve effectually it. The lite and photocell then motion a fraction parallel to the centrality of the drum for the next line to exist scanned. The curved drum keeps the film to light source distance abiding, and avoids issues with reflections.

How to scan artwork with a flatbed scanner

Before you kickoff

Y'all need a flatbed scanner installed and connected to a estimator system.
Before use, carefully clean the scanner glass with a damp cloth or glass cleaner and dry.

Fix the epitome and software

Put the impress confront downwards on the drinking glass. Ensure that the actual impress area is parallel to the edges of the scanner.
Get-go the scanner software. On some scanners there is a scan button, or there may be an import part on your images processing software, or a dissever scanner program.
If your scanner software does not automatically run a preview, do and so (unless y'all are using VueScan — see Tips beneath.)
If your picture is skewed, adjust the alignment and repeat the preview.
On the preview, apply the mouse to outline the desired scan area.

Choose colour and resolution

If you are going to apply Photoshop (or other image manipulation), scan all images every bit 'millions of colours'. Otherwise use this for colour and grayscale for black and white.
Conform the scanner resolution to requite an appropriate file size in pixels. For printing, scan to get 300 pixels per inch of final print size. For web, create a scan with largest side effectually 900 pixels.
Try the auto-exposure button if there is one in the software, then adjust brightness and contrast if needed. On some scanners, resetting to default will requite good results.
For color pictures, set up whatsoever colour controls to the default values unless you are scanning straight to a printer.
If your scanner has a setting that allows you to improve shadow separation, utilise it.

Finally, scan and save your artwork

Scan the images, saving in TIFF, BMP or PCX, but not every bit JPEG.

Tips

Always gear up the size measurement on the software to read in pixels when making a scan, unless you are scanning direct to a printer.
Third-party scanning software may produce better results than that supplied by the scanner manufacturer.
Never browse at a higher resolution than the actual optical resolution of your scanner. Never utilise whatsoever 'sharpen' command in the scanner software.

Scanning work larger than your scanner

Have the cover off the scanner
Place artwork face downward on scanner.
Scan the first quarter at a resolution of at least 300 dpi, preferably higher, taking nifty intendance to marshal the artwork squarely.
Proceed to scan all four quarters with exactly the same settings and again, have great care to align the artwork squarely.
Open up each of the quarters of the painting in Photoshop.
To remove any canvas pattern, etc. optionally:
- Utilise Filter -> Blur -> Gaussian mistiness, take the radius at between 5–10 pixels
- If you scanned at more than 300 dpi, reduce each quarter to 25%
Get to Image
- Become to Epitome Size – the window volition look like this (Annotation: Make sure that Constrain – Proportions box is checked: Paradigm Window
- Change inches to percentage by pressing the triangle next to the discussion inches.
- Modify width to read 25% (when the Proportions box is checked, both the width and height volition be reduced by 25%).
- Press OK.

Brand each of the quarters 25%.
If necessary, go to Paradigm -> Rotate, and select the correct number of degrees so that it volition be right side upward.
Now information technology is fourth dimension to put your painting together.
- Go to Paradigm -> Canvas Size, alter the width to 5 inches and the height to half-dozen inches. This will give you enough room to get together the painting.
- Next, add together 3 more layers to the paradigm, one for each of the quarters.
  - Brand sure the Layers Palette is open up.
  - If information technology isn't, go to Window -> Palettes -> Show Layers to open it.
  - Printing the triangle until the bill of fare pops out and choose New Layer.
- Using the Marquee tool, move the bottom left side of the painting to the lesser left side of the screen.
- Copy each of the remaining quarters and paste it into its ain layer in your assembled image file.
- You tin can now motion around each of the quarters until they all friction match upward with each other by selecting the layer that information technology is on and using the Move Tool (tip: you can use the arrow keys) to motility each department by a very small amount).
- When you are happy that all the quarters line up, go back to the Layers Palette and press the triangle once more. This time choose "Flatten Paradigm" and your quarters will now be pasted together.

At this point, yous can handle this epitome like whatsoever others you accept edited, however you might need to trim it a petty, sharpen it, arrange the colors, change the size to fit your web folio, etc.

Which scanner to purchase

Scanner technology is improving all the time, then it's difficult to keep current with recommendations. Apart from following recommendations, the main factors to consider are the optical resolution and bit depth, only any new scanner is likely to exist able to produce adequate results.
