![]() ![]() The only way to get around that is to manually go in and mask out all the unwanted areas of the image, which is both time consuming and not entirely accurate, whereas Touch7 does everything with a single click of the button, in seconds. ![]() Grey balance is also critical for printing – using either the yellow or magenta channels based on duplicating either the magenta or yellow, could contaminate the background in the image below, and make this image look pretty terrible. As you can see, the pink colours have been removed from the original RGB, so that you only print with Neon pink in those areas, instead of adding neon pink on top of the magenta as an overprint!!! In the visual below, we have shown the magenta and yellow channels within an image – as you can see, yellow and magenta are in almost every region of the image – whereas the Touch7 Neon plugin isolates and extracts out only the pink or yellow pixels within that image – this is done using a process of subtracting each pixels hue value from the image, to leave only the yellow and pink pixels – the reason we recommend to adjust the touch7 separations after they are created, is because colours like "pink" are a shade of Magenta, so it can only extract out the hue value for pink, which is not solid! And, when you have a colour that is not perfectly pink, for example, it might have a slight blue tint to it, or even a colour that moves towards the purple end of the pink colour spectrum, then you have to remove the blue pixels from that colour to leave only the "true" pink pixels within the image – The Touch7 plugins use a mathematic algorithm to extract out that data, and then you have the freedom to boost up those colours to make them more solid, if you wish to!Īlso, Touch7 has SCR buttons – Source Colour Removal – The SCR buttons subtract the neon separations from your original image (a bit like UCR, but for neons!) – if you print the pink or yellow neon inks/toners on top of an image, that's overprinting and you increase the saturation, but then you might start to go above the total ink limit for the press – if you print pink over red colours, you can also contaminate that colour – so, as an example, if you have a customers image, of a lady in a red dress holding some pink flowers, Touch7 will only affect the pink flowers, whereas using the magenta channel would also put pink into the red dress, which would change the colour of that dress!īelow an example of the SCR button in use. ![]() Great question – Let us explain both visually and technically how Touch7 works.įirst, you need to consider where "yellow" and "magenta" are used within a typical image – Yellow is a colorant that is found in greens, green/blue hues, reds/oranges, grey tonal areas, shadows etc, in fact, this is true of most colours used in printing, as each primary is used to create everything from skin tones to grey balance – so, if you use an approach of just duplicating the yellow or magenta channel, then those neon toners may contaminate other colour groups within an image. "get info" on the Adobe Photoshop application and switch on "Open using Rosetta" this will then allow the application program to open up using the original apple code and will therefor allow you to continue to use plugins and extensions.Ī question was posed to our technical team "Why do I need Touch7 Photo NEON, when I could just duplicate the magenta and/or yellow channels from an image, and print those with the Neon Pink or Neon yellow?" There has been no noticeable speed differences between the silicon version of Photoshop or switching to Photoshop in Rosetta mode, with no loss of function.ġ. However, simply opening Photoshop in Rosetta mode will open Photoshop in the original apple code and allow you to continue to use third party plugins, whilst developers learn the new apple code and redevelop their products. In the meantime customers running the latest Apple Macs with the M1 chip will need to open Photoshop in Rosetta Mode in order to continue to use the Touch7 Photo plugins – this is because Adobe Photoshop on the M1 chip computers no longer supports HTML5 plugins/extensions and there is no "extensions" menu. ![]() *** We are currently redeveloping all our plugins for the new Apple UXP *** ![]()
