Printing and handling guidelines



> Screen rulling:

 

These papers are perfectly suited to litho printing. For half tone printing it is not usual to exceed 150 lpi but with careful ink control rulings of 200lpi can be used. When four colour printing there may be some benefit in using Under Colour Removal techniques and/or the use of 'Stochastic' (FM) screening technologies.

 

> Varnishing and sealing:

 

Be certain the printing inks are suitable for UV varnishing and ensure they are thoroughly dry before sealer and varnish application. A gloss varnish is not easily achieved. Best gloss results are achieved by printing UV Silk Screen Matt varnish and then overprinting with gloss UV varnish. Other machine varnish applications are not advisable as a visual effect will not be achieved. Consider printing a clear hot foil as an alternative. Sealers
can be used to give minimal protection to printed material to help avoid marking when further processing is required. Be certain the printing inks are suitable for sealer application. Best results are obtained when applying the sealer after the inks are thoroughly dry.

 

• Embossings: may be done with relative ease in the Recycled and Original grades. It is recommended to have the corners of the die rounded off to help prevent creases forming from them. To emboss an image in an already embossed sheet, it may be necessary to plate sink the original embossing before stamping the new one. This is very true for the strong Keaykolour textures like Cedar or Twill.

 

• Hot foil blocking: Keaykolour Recycled and Antique accepts hot foil blocking easily. The embossed versions of Keaykolour also accept hot foil blocking but due to the uneven embossed texture some image detail will be compromised. If a fine image is to be blocked on to a Keaykolour embossed product it is recommended to plate sink the area first.

 

> Film laminating:

 

Only smooth/wove finishes can be film laminated. Although due to the rough open texture some 'silvering' will be evident after lamination. To help reduce 'silvering', increase the laminating pressure and apply excess adhesive if possible. The increased amount of adhesive will probably extend the time required to acheive a good bond with the lamination.

 

• Creasing: The board weights (160gsm / 200micron and above) will require pre-creasing by a channel and matrix system before folding to help avoid cracks appearing at the fold. Most of the textures can be creased and folded in this way without problems. However the Cedar texture may fracture at the fold slightly and depending upon the crease preparation the fold may wish to follow the embossed texture.

 

> Environment:

 

The entire Keaykolour ranges are FSC certified and in recycled grades made with superior premium post consumer pulp.
