Hi-Fi printing is a unique offset printing technology that allows photographs to be printed in extremely high quality — with outstandingly rendered details and colours that are boldly alive.

It is especially suitable for photo calendars, high-end catalogues and other prestigious print material.

Technology

wide-gamut printing with stochastic rasterization

With Hi-Fi printing®, especially blues, purples and greens are much more intense. This is made possible by wide-gamut printing with a new-generation stochastic screen and specially pigmented CMYK inks from Japan. Thanks to the merging of these two advanced print technologies, it is now possible to reproduce photography in a quality never before seen in offset printing. The images feature sharp, detailed colour and subtle transitions. The difference is obvious at first glance — much like the contrast between an old TV and a modern full HD screen.

Wide-gamut printing

offset CMYK printing with a wide colour range

Hi-Fi printing® technology covers practically the whole sRGB colour range, with the exception of only the very limits. In rendering green and green-blue shades, the Hi-Fi printing® scale is considerably wider, with a broader gamut than its predecessor RGB. This is why Hi-Fi printing® is excellent for reproducing images dominated by these colours. Its superiority to old-fashioned CMYK is visible at first glance.

Stochastic screen

offset printing with a stochastic screen for sharp detail

Frequency-modulated rasterization (FM), also called a stochastic screen, differs from amplitude-modulated rasterization (AM) in that it always works with the same printing points. With clusters of coloured dots instead of the regular structures of AM rasterization, the digital image data are interpreted much more perfectly. The image is not broken into the rosettes of traditional CMYK separations, eliminating undesired moiré effects, and the image is visibly sharper and deeper.

Japanese inks

specially pigmented CMYK inks

The inks used for Hi-Fi printing® have been developed by a Japanese company and have different Lab values than ordinary CMYK. Especially in the azure and violet ranges, the colours clearly surpass even the best traditional CMYK offset printing. Based on tests and repeated measurements, there were unique ICC profiles for this wide CMYK.

How to prepare files

Hi-Fi printing® technology depends on properly prepared digital files. The source images or photographs must be saved in the Adobe RGB space with the highest possible resolution. Files prepared in the ordinary manner, according to the PDF X-1/a standard, cannot take advantage of the wide colour range of the subtle screen that Hi-Fi printing® offers.

  • Use the Adobe RGB space — do not convert to CMYK. The Adobe RGB colour model is important for using Hi-Fi output’s broad colour space.
  • The original or higher image resolution is ideal for the subtle stochastic rasterization. Do not change the resolution to 300 dpi, because details will be lost in reproduction. In some cases, we recommend upscaling, i.e. increasing the resolution. We use a special tool for this purpose. We will be happy to tell you how to do it.
  • You can freely combine RGB images with CMYK objects. Only Adobe RGB objects exploit the full potential of Hi-Fi printing®. CMYK objects are printed in the standard manner.
  • It is important to set the export to PDF, as opposed to a standard one (such as PDF x/1A: 2001), there are some essential changes here.

Set the standard header to None, Compatibility: Acrobat 7 (PDF 1.6).

      1. Compression: Do not downsample colour images with greyscale, Compression JPEG, Image quality Maximum.
      2. Marks and bleeds: Tick Crop marks, bleed 3 mm, Offset 3 mm.
      3. Output – Colour conversion: No colour conversion.
