Below you will find an overview of the most frequently asked questions.
COVER MATERIAL CHARACTERISTICS
TEXTILE VERSUS PAPER
The textile fibres make textile materials stronger than paper, preventing them to tear easily, especially when it concerns large and heavy books. The use of textile is therefore also more durable. In addition, a textile cover material gives extra value to your product due to its luxurious appearance.
WHAT REQUIREMENTS MUST OUR COVER MATERIAL MEET?
Our cover materials need to bond well with cardboard when the prescribed adhesives are applied, while not allowing the adhesives to seep through. The materials mustn’t be susceptible to scratching, give off lint and curl during the mechanized binding process or the preceding printing process. They can be processed both on the binding machine as manually and stay strong at joints.
WHY DO YOU USE THIN INSTEAD OF THICK PAPER LINING?
Paper backing provides extra stability, prevents stretching and fraying, but mostly it prevents glue seepage. With the paper on the backside, the cloth behaves more as paper, meaning, it becomes easier to cut, bend and work with. Yet, when you use thick paper the material becomes stiff and won’t bend as easily as with thin lining.
Continuous tests and years of experience show that thin lining with high-quality non-acid paper of 30 gram is most suitable for further processing and possible cardboard backing. We don’t charge for the paper backing as it is inherent to the product.
WHICH MATERIAL IS MOST SUITABLE FOR OFFSET PRINTING?
We advise to use our offset collection Printex, Imprimex and Reprotex as these are treated with a top coating specifically developed for offset. For more information please refer to the Printing Datasheet in the Download centre.
WHAT IS THE DIFFERENCE BETWEEN PRINTEX, IMPRIMEX AND REPROTEX?
Printex possesses a tactile woven, natural look. Imprimex and Reprotex are fully coated and varying in thickness and strength.
Printex, Imprimex and Reprotex have been specifically developed for printing in offset. When printing in offset litho on Printex, Imprimex and Reprotex we advise the use of offset inks developed for printing on non-absorbent substrates like synthetic materials. These inks are oxidative drying inks, to be used with as little water as possible. Try use a multi dryer (2-5%). Our offset materials are also suitable for waterless offset.
WHICH MATERIAL IS MOST SUITABLE FOR UV PRINTING?
This printing technique is most suitable for smooth and coated substrates, such as Buckram Premium, Buckram Light, Fancy, Metallium, Finesse etc. On the coarser materials with a more ‘open’ texture, such as Halflinnen Dark or Regina, the ink tends to be soaked into the fabric, which might deliver blurred prints. We advise to use denser and/or coated materials when choosing UV printing.
Thanks to a special coating, Buckram Premium in white is in particular suitable for UV printing.
WHICH FIBERS ARE USED AND WHAT ARE THE ADVANTAGES / DISADVANTAGES OF THE DIFFERENT FIBERS? The majority of our collection is made from rayon. Rayon is made from purified cellulose which is created from wood pulp (beech wood). Rayon is basically less strong than polyester or cotton, therefore we paperline it. We also use 100% traditional cotton and a combination of cotton and flax that gives it a rustic appearance. Our Halflinnen Dark and Halflinnen Light are bearing the Masters of Linen mark. In addition, we weave a combination of cotton and polyester that gives a high level of tensile-strength and wear-resistance.
WILL THE CLOTH MARK
We advise to wrap the end-product in plastic when being transported or stacked to avoid stains and scratches on the material.
COATED VS. NON-COATED MATERIAL, WHEN TO USE?
When making a product for heavy use we advise our coated materials. Besides the high tensile strength and wear-resistance it can also be wiped clean with a damp cloth which makes it also very suitable for menu cards.
If you want to emphasize the beauty of the natural textile texture and add value by means of printing, embossing or foil, you can choose from a wide range of different uncoated materials in our collection.
Our materials are mainly used for high-end coffee table books, luxury and premium packaging, stationery, pattern books and the hospitality and photo industry.
WHICH GLUE TO USE?
Cloth over cardboard: animal or hotmelt bookbinding glue in case of a book case machine. Synthetic glue in case of handbook binding or packaging.
Cloth to cloth: either animal or hotmelt glue.

WHICH MATERIALS ARE FSC CERTIFIED?
Most of our cover materials are paper backed. For this process we use FSC certified paper only. The rayon and cotton based cover materials Brilliance, Dubletta, Natuurlinnen, Buckram Light and Halflinnen Dark are fully FSC certified.
IS THE PRODUCT RECYCLABLE?
For the dyeing and coating process, as well as other finishing processes, we follow REACH directives and select the most environmentally-friendly ingredients. The lamination paper is acid-free and made of wood that is produced in accordance with FSC standards, the adhesive used is a polyvinyl acetate and acid free. However, as our materials are semi-finished and sometimes undergo treatments afterwards we cannot make any statements about this.

HOW TO CALCULATE HOW MANY METERS YOU NEED FOR SHEETING?
Our machines need 2.5cm on both sides to hold the material, this means that we always work with a gross and net width.
As an example we take Brillianta: gross 135cm so usable 130cm.
1000 sheets in width 32.5cm x 70cm
We can cut 4 sheets of 32.5cm from the width 1000 sheets / 4 = 250
250 x 0.70 = 175 meters.
LONGGRAIN OR SHORTGRAIN?
Only when there is a large difference in the warp and the weft, such as with Regina and Natuurlinnen you must consider this.
WHAT DOES NM MEAN IN THE SPECIFICATIONS ?
E.g. warp Nm50 and weft Nm40
the Nm stands for ‘normal metric’ – which is based on 1000 metres of yarn per kilogram.
The higher the number the finer the yarn.
The majority of our colours are on stock.
We need approximately 3 weeks for the production of natural cover materials and 4 weeks for the coated types. In case of sheeting we need an additional week, this, however, depends on the sheet size and quantity.
We can detect any colour based on a Pantone colour number or a piece of fabric / paper and make a lab sample. The first production becomes the standard for the recipe of this specific colour. The minimum order quantity for a special colour is 1500 meters.
Do you need a special textile material for e.g. limited edition of books or premium packaging boxes? Our highly experienced team of experts will be happy to assist you in specifying the desired colour/weave or/and coating for your project. Upon request, we manufacture bespoke materials with the minimum order quantity of 1500 metres.
- Water & stain repellent treatment
- Waterproof bonding
- Hotmelt or thermo coating
- Flame-resistant treatment
Upon request we supply A3 sheets or meters (max. 3 meters per colour).
CUTTING / SLITTING TO SIZE
We can supply sheets cut to size to a max of 100 x 140 cm. We can also supply narrow coils from 2 cm upwards and with coil lengths from 100 to 500 metres.
