Custom Scanner Profile Service - Printed Media

These instructions guide you through correctly scanning a profile target so we can make a precise Custom Scanner Profile for you.


Our service makes things fairly simple for you because we do the really technical bit. That said, you will need to be familiar with your scanner's driver software and to following these instructions carefully. Please contact us if anything is unclear.

Outline of the Process

Detailed Instructions

Please make sure the glass of your scanner is clean before you start.

Most scanners have similar controls, that do such things as set the resolution of the scan, brightness, contrast etc. For this reason make/model specific instructions are not provided but you should learn what you need to do by following our example of an Epson Photo Scanner.

Accessing the Scanner Driver

This can be done directly with the manufactures software ('Epson Scan' in this case) or sometimes via a program such as Photoshop. Our example focuses on the manufacturers software.

Settings at a glance

Select the most advanced mode (in this case "Professional Mode" to ensure that you have full control over all the scanner settings. This is important because you want to force the scanner to it's native behaviour rather than allow it to try to enhance images.

Set the document type / exposure type to Reflective / Photo.

Bit depth should be set to the maximum available (48-bit color). 48 bit really means 16 bits per channel so if your scanner only offers a choice between 8 and 16bit, choose 16bit.

Set resolution to 300 PPI. NB. This is sometimes incorrectly referred to as DPI.

Target Size = 'Original' which means don't scale the scan up or down.

Unsharp Mask (Digital Sharpening), Descreening (deals with moiré) and Color Restoration must all be switched OFF.

Colour and Tone. There are usually some controls for making colour / tone adjustments and we want to ensure that these are all turned off or non effective. Often (as with this scanner) there is a global setting of 'No Colour Correction' that can be set (Scenario 1 below) alternatively you will need to individually disable or set a zero adjustment for any scanner controls that deal with colour or tone. (Scenario 2 below).NB. Use either Scenario1 or Scenario2 - you do not need to use both.

Scenario 1

Drivers WITH a 'No Colour Adjustment' setting:

Our scanner driver has a button labeled "Configuration" (bottom of main window) which brings up a new window as follows

Here we have selected the option for "No Colour Correction" and set the Auto Exposure to Low. For our scanner 'Low' is miss-leading because it actually means OFF!

These 2 settings together are enough to tell the scanner driver not to make any colour or tone adjustments. Any controls that adjust colour, tone , histogram etc have all been de-activated.

Scenario 2

Drivers WITHOUT a 'No Colour Adjustment' setting

If your scanner does not have a "No Colour Correction" setting you will need to review each of the specific image adjustment settings available and make sure they are disabled, zeroed or OFF. Our example scanner offers specific settings for Histogram,Curves and Colour. Below we show you how to make appropriate settings.

After Clicking the histogram button. The histogram window opens and looks like this.

You need to do just 3 things:
  • Slide the left-most triangles to zero on both the Input and Out sliders.
  • Slide the right-most triangles to 255 on the Input and Output sliders
  • Slide the middle triangle until 1.00 appears on the text box just below it.
The Histogram should now look like this.

A de-activated Curves adjustment is represented by a straight line graph. There may well be preset called 'linear' which sets the 'curve' to a dead straight line running from 0 to 255. If there is no preset you will need to do this manually, which is usually a matter of dragging the first data point on the curve to the bottom left corner (0,0) and dragging the last data point to the top right (255,255). There should be no data points in between.

Straight line (linear) curves adjustment.
Color Adjustment. You just need to set everything to zero.

Scan output settings

Set TIFF as the type of file to output and select a folder in which to save it.

Making the scan

Now you are ready to make the scan. Don't forget to do a preview first to make sure you have placed the target squarely on the glass and check that the Selection Marquee (area to be scanned) is set wide enough to not crop any of the patches of colour from the target.

Check the scan and Email it to us.

Open the completed scan and check that it has processed properly. It should be reasonably clean of dust, hairs and so forth. We will do a bit of digital cleaning at our end but there is a limit to what we include in the price. Make sure your scan has not cropped out any of the patches.

You can email the scan to

We aim to email the profile to you within 1 business day (usually the same day).

Using your new scanner profile

Once you have received your new scanner profile you need to use it when you scan. It's a quick and painless procedure which you can read about here.
