Creating Epson ABW Paper Grey Curves Just Got Easier

Epson ABW Grey Curves

When printing black and white images through the ABW driver, we don’t use the standard ICC color profiles because those profiles are based on the RGB driver, not the ABW driver. In fact, in Photoshop we use the “let the printer manage the colors option”

This means that your images’ RGB values are passed directly to the ABW driver unmodified. For example, if you place the eyedropper in Photoshop over a pixel and find that it has RGB values (240,240,240), then (240,240,240) is exactly what Photoshop will give to the ABW driver.

There are a few issues with this approach, and they all have to do with the fact that the output process isn’t color-managed so in order to compensate for the discrepancy, we build and use a custom black-and-white correction curve with the Paper Grey Curves Photoshop Plugin.

Creating a custom print curve with the Paper Grey Curves Photoshop plugin will help to iron out the wrinkles from the discrepancies we get between the pixel values we send to the Epson ABW driver to the pixel values we see in the final print.

Plugin Components

The plugin comprises of three main components, each one is extremely intuitive and easy to use.

Paper Profiles
Edit Paper Profile
Correction Curve Creation

We start by creating a paper profile for the paper you are using, then we create the step wedge from within the plugin, print it and let it dry.

We then enter the data from the step wedge patches and create the correction curve.

It really is that easy.

Paper Profiles

Create individual paper profiles for your favourite papers you like to print on with the Epson ABW driver.

No More Having To Hunt Around For The Step Wedge Data.

By storing the information form the measured step wedge patches directly into the paper profile dramatically speeds up the process when creating the final correction curve.

Create as many profiles as you need. You also have the option to export and import the profiles which is ideal for creating backups should you ever need them in the future.

Create Step Wedge

Creating the step wedge is the second part of the process as we use the values from the print to create the final correction curve.

After the step wedge is printed and given time to dry each of the patches are measured with our hardware measuring device.

In version 3.1 we have also included the option to use a flatbed scanner to scan the step wedge and the plugin will automatically measure the values for you and write them into your slected profile.

Create Correction Curve

Creating the correction curve is extremely easy in version 3.1 of Paper Grey Curves because we no longer rely on an external spreadsheet to perform the complicated calculations for us as they are now built right into the plugin.

Choose between creating the curve directly onto the active document or choose to have it created onto a new blank document.

Built In Video Tutorials

Accessing the mini video tutorials has never been so easy

By using a custom built video player, it has allowed the mini video tutorials to be brought right into the heart of the plugin.

Version 3.1 now uses intelligent detection algorithms to measure each of the 11 scanned patches and then populates the numbers directly into the created paper profile.
