You can use your own preferred inks, however, if you wish to print using inks recommended by Touch7, we recommend the following inks:

Touch7 gives you the ability to selectively enhance your images. Simply choose which spot colour(s) you would like to create, by clicking the appropriate coloured button.

Watch our tutorial video if you need help on how to assign ink values to your spot channels.

You have now assigned the specific press partner ink values to your spot channel.

TIP: You can create an action set of the above process to speed up your workflow.

SCR is a little bit like UCR, but whereas UCR restricts the amount of ink printed in the shadows, SCR is used to remove the equivalent hue value of the Touch7 spot colours from the original source image – this feature is particularly useful when you wish to extract out a range of colour from your image, that you wish to be swapped out for the ECG ink on your press.

How to process an image using the SCR buttons.

Whenever possible we advise working with original RGB images, as these images have a larger colour gamut and therefore have more data to extract out – Images that have been converted to CMYK have a reduced colour gamut and therefore there’s less colour information to extract out!

Also, just because an image says it’s RGB, doesn’t mean that it has always been an RGB image...Sometimes people convert CMYK images to RGB, but this still retains the same reduced colour space of the original CMYK image – Therefore, it’s a good working procedure to edit your spot separations after they have been extracted, to ensure you are getting the best out of your images.

In the image above we are going to extract out ORANGE, GREEN and BLUE spot separations, using the Orange, Green and Blue buttons on the Touch7 Plug-in. However, because this image is in CMYK, some of the colour information will have been clipped/reduced - this is because CMYK has a smaller colour space compared to RGB, so when an image is converted to a smaller colour space, it loses some of that colour saturation. Touch7 can be used to add more colour back in to your image.

The image above shows how using “LEVELS” in Photoshop, you can add more colour to your ECG separations.

The Touch7 plug-in can only extract out colour information that is in the image. If your image has very little ECG colour data, you can add more colour into your design by using LEVELS in Photoshop. We would advise to increase the amount of colour in your separations by controlling the shadow point on the histogram, as shown in the image above. When you are happy with your separations, click on OK.

Touch7 can be used to process images within a customer supplied PDF – However, due to the limitations of Adobe Acrobat it’s only possible to process one image at a time.

Step 1
Open your PDF file using Adobe Acrobat (requires a full version of Adobe Acrobat Pro/DC)

Step 2
Using the Adobe Acrobat Tools, select the “EDIT PDF” function.

Step 3
Select the image you wish to convert and go to the “EDIT USING” feature, and select your version of Adobe Photoshop – If you do not see a version of Adobe Photoshop listed, navigate to your preferred Photoshop application, using the “Open with...” option.

Step 4
Your image will then open up in Photoshop – Next, process the image using Touch7 Photo ECG, and once you are happy with your file conversion, save and close the image.

Step 5
Next, go back to your PDF in Adobe Acrobat and your image will automatically update, bringing in the extra Touch7 spot colours.

When the Touch7 plug-in processes an image, it needs to create “History snapshots” at various stages of the file conversion. Once you have processed an image, if you wish to undo what you have done and try a different Touch7 preset button, you would first need to delete the previous history snapshots.
