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/C73hc 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.
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/C73hc, 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/C73hc 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.
“Standard mode” for RGB image
The colours outside of CMYK colour space is narrowed to colours that CMYK toner can reproduce. Some highly saturated colours are not reproduced and lost.
High chroma toner (C83hc/C73hc)
The printed colours are close to result printed with CMYK toner. However, light blue, green and pink areas are more vivid and clearer than that produced by CMYK toner.
High chroma toner (C83hc/C73hc)
With “Saturation mode”, maximum colour space of the high chroma toner is utilised. The colours are more brilliant, clear and impactful.
High chroma toner (C83hc/C73hc)
“Soft mode” (IC-605 only)
“Soft mode” is provided to improve reproducibility for shadow area, when the quality is not satisfied.
“CMYK profile” (ex. Japan Color)
Normal CMYK colour.
High chroma toner (C83hc)
“CMYK profile” (ex. Japan Color))
Normal CMYK colour. The quality is very close to that of CMYK toner.
By utilising the wider colour gamut, colours closer to RGB can be obtained. That is good for studio photo, photo book, nature photo, illustration, CG, web to print and so on. The printed image will be more natural and impressive compare to image that is created with ordinary CMYK system. The expansion of spot colour reproduction is useful for printings with
company logo colours and the vivid and strong colours can be utilised to create impactful POP, package, poster and so on that makes big
Studio Photographs, Photo Books, etc.
The wide colour-gamut toner used by AccurioPress C83hc/C73hc utilises colour materials featuring greater saturation and brightness than conventional CMYK toners
- Enabling realisation of smooth skin tones with reduced skin texture roughness and less graininess
- Making it ideal for studio photograph and photo book printing.
- High-quality prints can also be supplied for items such as small-lot cosmetics or apparel catalogues
Nature Photographs, Apparel Catalogues, etc.
Addition to the conventional CMYK colour gamut, one of the greatest features of AccurioPress C83hc/C73hc is its ability to reproduce colours difficult to realise using a CMYK printer such as sunset purples, the pink of flowers, high-key greens and blues. This makes it possible to express the intent of photographers and designers, for example, with greater fidelity in prints. Moreover, prints of items such as apparel catalogues or fashion photographs can be supplied with colours close to the originals.
Academic Reports, Analytical Photographs,CG, Office Documents, etc.
Because images seen on screen, such as office documents and CG, are configured with RGB, some colours cannot be reproduced with conventional CMYK printers because they have a narrow colour gamut. High Chroma Toner, however, is capable of reproducing colours closer to the image seen on screen and thus also demonstrates its prowess for presentation documents.
Business Cards, Shop Cards, POPs, DM, etc.
The excellent spot colour reproduction with the wide colour gamut provides bright and clear company logo colours for name card and shop card especially for light blue and green. AccurioPress C83hc/C73hc provides the capability to create items such as impactful business cards or POPs using colours not often seen. AccurioPress C83hc/C73hc enables utilisation of colours that users have hesitated to use in printing up to now, realising the ability to supply distinctive printing services. Moreover, differences between colours on monitor screens and prints can be minimised when approaching customers with DMs or cross media.
Designs, Illustrations, Coterie Magazines, etc.
Wish to use impactful colours on packages, but hesitate to do so because such colours cannot be produced with ordinary printing. At times like this, with AccurioPress C83hc/C73hc, small lots can be printed with abundant colour reproduction and high productivity using preferred colours. Prints faithfully reproduce the colours that satisfy the creator’s particular preferences for animation drafts, illustrations or coterie magazines featuring a wide variety of colours such as purples and bright greens.
Regular Prints, Catalogues, etc.
Because it also covers most of the CMYK colour gamut, High Chroma Toner enables the creation of beautiful prints of ordinary CMYK files with ease simply by applying CMYK profiles.
Various screens and smooth gradation owing to sophisticated dot control

Real-time colour & registration monitoring and correction
Colour tone and front-to-back registration are monitored and automatically corrected in real time without degrading productivity. As a result, colour fluctuations and registration misalignment are controlled to a minimum, which helps provide high quality print products in a stable manner. Stable results are ensured in printing of company logos for which the colour stability is essential, and cards, page numbers of booklet and ruled lines for which accurate positioning is essential. In addition, print waste caused by instable colour and registration is minimised, contributing not only to cost reduction but also to improve customer trust.
Technologies to support the consistent quality
High precision registration mechanism
A registration swing mechanism capable of highly accurate detection of paper misalignment and skew is furnished, realising a professional finish for duplex printing that needs to be accurate for use in additional printing and for trimming/bookbinding. The mechanism also automatically corrects paper-feeding misalignment in the main unit tray, contributing to both improved quality and higher productivity. Paper conveyed in misaligned orientation is pressed against the registration roller to correct the misalignment, while the registration swing mechanism moves shifted paper into the correct position.
Real-time image optimisation with IDC sensor
This function controls image stability in short intervals during continuous printing by detecting density correction patches and dot diameter correction patches created on the intermediate transfer belt furnished with an IDC sensor, delivering stable high quality for a wide range of densities through 2 types of density calibration. Reducing print waste relating to colour reproduction helps not only to reduce production costs but also to enhance customer trust.
