The screen may look complicated but the settings, once made are normally left alone; the controller will just get on with the job in hand.
Pantone Colours (‘Spot On’ Option)
The Fiery controller has the ability to print Spot colours. They are normally referred to as Pantone Colours but not all can be printed as many Pantones colours use more than just CMYK Inks. Using the Fiery, users can produce Pantones that are within the Colour Range of the Copier using CMYK Toner.
What are Pantone Colours? Ready mixed inks used within the Offset Press environment. The inks can be purchased straight off the shelf ready to use, or an offset press operator can make up the chosen colour using various base inks. With the later option the colour accuracy is down to the experience of the mixer! There can be up to 17 base ink colours used to make Pantone colours including White ink. The CMYK process on a colour copier/printer uses just the 4 Toner colours - Cyan Magenta Yellow and Black.
Corporate colours are often chosen from the Pantone library. Some companies deliberately choose colours that are not able to be printed or recreated using just CMYK which stops people trying to copy or counterfeit goods. Most applications that support named colours send the print job to the printing device with the named Colour as well as the application’s own interpretation of CMYK data for that colour. Different software applications interpret the CMYK data in different ways with the result that prints from different applications often present Pantone colours in different ways.
The Fiery controller works differently, it ignores the CMKY data for the named colour and uses its own reference table. When different applications demand the same named colour, the Fiery outputs the same colour, achieving a more consistent output.
Not all Pantone colours can be printed using just CMKY Toner, so please do not assume that all colours will be printed accurately, the Fiery controller will print Pantone colours that use Process colours (CMYK) within the colour capabilities of the engine being used. So another manufacturer’s machine may not be able to print certain colours that we can.
Auto Trapping (Option)
Auto Trapping is an option for the Fiery version of the product. When this option is fitted the Fiery controller looks at the print data and looks for areas that might produce a white Halo around an image. Where found, the controller will adjust the print data to “Fill in” the area concerned.
This sample illustrates a File that has been printed without Auto Trapping. You can see a white halo effect where text has been overlaid over a coloured background.
The nest sample illustrates a File that has been printed with Auto trapping switching turned ON. The white area around the edges has been eliminated by “Filling in” this area.
