Power of colour reproduction
Colours seen on displays or images shot using a digital camera can express a wider colour gamut than CMYK used for ordinary printing. For this reason, because CMYK ink or toner has a narrow colour gamut of colours such as pink, purple and bright green, colours tend to become dull or muddy when printing RGB images.
As the world’s only printer that uses a new toner free of the restrictions imposed by the colour gamut of ordinary toners, AccurioPress C83hc offers a solution to such problems.
Enhanced light blue/green
With combination of the wider colour gamut and higher L* value of high chroma cyan toner than that of CMYK toner, clear and bright colours can be maintained especially for bright blue and green. CMYK toner loses the colour when the toner amount is reduced to express the brightness or loses the brightness when the colour is tried to be maintained.

Enhanced pink/purple/magenta
By utilising high chroma magenta toner, vivid and clear pink and purple colours can be obtained.
The large colour difference between CMYK printing and RGB colours in monitor has been one of big weak point of CMYK printing systems. For example, flowers with pink or purple colour is always dull and muddy compare to colour expected.
Graphic designer and illustrator sometimes have to give up to use these colour they want use.
High chroma toner get rid of the restrictions. The high L* value helps to create smooth and less graininess skin tone that is good for photo related applications.
Also, the vivid colour make possible to create eye-catching poster, POP and so on that makes big differentiation from other printers.

Print profiles to utilise features of the high chroma toner
With “Saturation mode” of AccurioPress C83hc, the maximum colour space of high chroma toner is utilised and customer can experience the new world of colour reproduction that has never realised with ordinary CMYK systems. Of course, C83hc can print with ordinary CMYK colours with “Standard mode” because the high chroma toner covers most of colour space of CMYK toner. So, the customer can make print products with normal CMYK colour or high chroma colour with one system.
