Spectra7 – Extended Colour Space in Offset Printing

More colour for creative demands

Spectra7 is our answer to the colour expectations we encounter again and again. Designers, graphic artists, photographers and creatives who care deeply about colour would ideally print everything using Pantone colours.

In traditional offset printing, however, the number of Pantone colours that can be used is limited – at least in theory.

Our in-house developed printing technology Spectra7 expands the colour space of offset printing by about 30%. In addition to the four standard colours CMYK (Cyan, Magenta, Yellow and Key – Black), three additional colours are used: Orange, Green and Violet.

This allows us to reproduce up to 90% of all Pantone colours in a single print run.

For designers and colour enthusiasts, this opens up new creative possibilities. Instead of being limited to one or two Pantone colours, they can work with a much broader colour spectrum.

Spectra7 means more colour range, richer tones and greater creative freedom in offset printing.

Adding another 3 colors to CMYK enables an extended color space and overcomes the limits of offset. Particularly suitable for photo books, art books or product catalogs.

DUOTON

50 Shades of Grey

Black and white is not just black and white.
It may sound simple – but it isn’t.

To prevent a misty Venetian landscape or the gaze of a young girl in Cuba from looking flat or empty, black ink alone is often not enough.

Especially in photo books, art magazines and visual publications, black-and-white images should remain vivid and expressive. Even without colour, images should maintain depth, contrast and emotional impact.

That’s why we developed our own approach.

Traditional black-and-white printing typically relies on black ink with different halftone screens. With our duotone printing technique, we go a step further. By introducing additional colour pigments, we expand the tonal range and create significantly more gradations.

The result: refined grey tones – or in other words, 50 shades of grey.

This technique produces black-and-white images with greater depth, stronger contrast and a much richer visual effect.

It is particularly effective in high-end photo books and art publications.

TRITON

More than black and white

Similar to duotone printing, tritone printing aims to bring more life and depth to black-and-white images – even on paper.

Black-and-white photography is often elegant, high-contrast and timeless, even without multiple colours. To preserve this visual impact in print, however, more than simple grayscale printing is required.

With the tritone technique, we use multiple colour pigments to enhance contrasts and create finer tonal gradations. This results in images with greater depth, stronger intensity and a more three-dimensional visual effect.

Our goal is to transfer the moment as accurately as possible from the illuminated screen to paper – realistic, nuanced and with maximum image quality.

Tritone printing is particularly effective in photo books, art magazines and premium visual publications, where black-and-white images should retain their full expressive power.

This is a black that speaks volumes: the Triton printing process takes our B/W printing to a new level! By adding a third colour to duotone printing, we can print extremely high-contrast, detailed bla

UV Offset Printing

Brilliant colours without long drying times

UV offset printing is particularly suitable for printing on uncoated and natural papers such as book paper.

Due to the rough surface of these materials, colours printed with conventional offset processes can sometimes appear dull or less vibrant. UV offset printing solves this issue by maintaining strong and brilliant colours even on challenging paper surfaces.

The combination of high-gloss and matte coatings also adds depth and a subtle three-dimensional effect to the printed image, making visuals appear more dynamic and expressive.

Another important advantage is the drying process.
The inks cure instantly under UV light, allowing much faster finishing and processing.

UV offset printing therefore offers several advantages:

strong, vibrant colours on uncoated papers
instant drying through UV curing
low odour during production
durable and resistant inks
environmentally friendly printing process

This technique is particularly effective for high-end print products, magazines and photo books, where colour intensity and image depth are essential.

INTENSO+

Deep colors

INTENSO+ is another printing technology developed by LONGO that expands the colour space of offset printing and pushes the traditional limits of the process.

This patented printing method increases the available colour space by approximately 20%, allowing colours to appear more intense, vibrant and true to life.

The result is deeper blues, richer greens and overall purer colours. Oceans appear more immersive, landscapes more vivid and products more realistic.

INTENSO+ is particularly effective for fashion photography, product imagery and high-end visual publications, where accurate and powerful colour reproduction is essential.

With INTENSO+, offset printing achieves greater colour depth, stronger contrasts and exceptional colour brilliance.

Intenso+ is a printing process that we have developed and patented to bring maximum reality to our prints, thanks to its 20% higher colour space. This allows us to print colours of such high contrast
