ACRYLITE® Digital Print Pop Touch Technical Information

TECHNICAL INFORMATION ACRYLITE digital print pop touch Extruded Sheet Masking Masking is applied on both sides of the acrylic to protect the material. The product utilizes a special low-static film masking to prevent interference with the digital printing process. The textured side has a clear masking allowing for quality checks of the printed sheet without removing the masking. The masking on the gloss side of the acrylic is a low static white recling polyethylene that protects the sheet during fabrication processes. Packaging Product ACRYLITE digital print pop touch acrylic is double-sided for first and second surface printing. It features a heavy matte textured first surface that meets ADA compliance standards. This sheet is specifically manufactured with enhanced adhesion properties for UV curable inks. Both sides have a printable cap layer that create a superior bond with the ink. Its optimized for wide-format printers with Braille and 3D graphic printing capabilities making it perfect for creating Braille ADA-compliant and architectural signage. ACRYLITE digital print products are also available in various colors and properties including markerboard and non-glare surfaces.

These are commonly found in retail healthcare and institutional settings. ACRYLITE digital print pop touch 4098A Technical Information 1124 This material ships flat in special packaging that controls moisture and allows for long term storage prior to opening. The packaging should be kept sealed during storage to minimize warpage due to moisture absorption. Storage Skids of ACRYLITE digital print pop touch are shipped with two layers of

polyethylene film overwrap that protects the sheet from dirt and moisture. The overwrap should be left intact during storage to minimize warpage. Sheet must be stored horizontally to maintain flatness. Sheet surfaces should be kept free of saw chips and other debris which can penetrate the protective masking and cause indentations in the sheet. Also it should not be stored near heat sources as heat tends to soften and deform the sheet or near any source of moisture as that may lead to warpage. Fabricating This sheet can be fabricated using the same machining parameters and equipment that are recommended for use with ACRYLITE acrylic sheet refer to ACRYLITE extruded fabrication briefs except flame polishing. In some instances better results can be obtained if the orientation of the printed surface is taken into account during fabrication. ACRYLITE digital print pop touch Extruded Sheet Cleaning Mounting This sheet can be cleaned with a solution of mild soap or detergent and lukewarm water or ACRIFIX AC1010 cleaner. Use a clean soft cloth applying only light pressure. ACRYLITE digital print pop touch can be mounted to most rigid surfaces. Select the proper thickness of sheet to avoid unwanted distortion of the printed acrylic. Mechanical fasteners such as standoffs or button mounts may be used see the section below on Drilling and drill over-sized holes 2 times the bolt diameter located at least 1.5 times the bolt diameter from the edge. Avoid over tightening the screws to prevent distortion of the printed acrylic. Cementing Methylene chloride-based solvent cements such as ACRIFIX 1S0107 typically used for acrylic sheet fabrication work well when cementing ACRYLITE digital print pop touch. This permits the use of other acrylic products including acrylic profiles in conjunction with ACRYLITE digital print pop touch. Cementing to the printed surface of the sheet is not recommended. Cutting with Circular Saws Conventional panel or table saws are recommended to cut AC

RYLITE digital print pop touch. Saw blades should be carbide tipped with a triple-chip design for plastics. Moderate feed rates 100-300 inmin insure a proper cut. The blade protrusion should be 1812 above the top of the sheet. Best results are obtained when the sheet is positioned so that the teeth of the saw blade enter the sheet on the printed surface. If positioned so the teeth enter on the other surface very slight chipping about 164 in size of the printed surface may occur. Cutting with Lasers Laser technology is being rapidly accepted by the industry for quickly and accurately cutting welding drilling scribing and engraving plastics. CO2 lasers focus a large amount of light energy on a very small area which is extremely effective for cutting complex shapes in acrylic sheet. The laser beam produces a narrow kerf in the plastic allowing for close nesting of parts and minimal waste. CO2 lasers vaporize the acrylic as they advance resulting in a clean polished edge but with high stress levels. Depending on the application annealing acrylic sheet after laser cutting may be needed to minimize the chance of crazing during the service life of the part. ACRYLITE digital print pop touch 4098A Technical Information 1124 Edge Finishing Edge finishers will produce very smooth edges on this sheet. However this may cause very slight chipping about 164 in size of the cured ink in printed materials. For most applications this will not be visible. The same depth of cut and feed settings as used with extruded sheet are recommended. Drilling It can be drilled with the same equipment that is used with ACRYLITE extruded sheet. Modified drill bits designed for acrylics plastics produce the best results. A proper backing material such as plywood or another piece of acrylic should be used when drilling the sheet. The backing material will help prevent chipping on the bottom surface. Rotational speeds from 500 1000 RPMs combined with feed rates in the 3 12 inmin range will usually

provide good results. Flame Polishing Flame polishing is not recommended. The flame will visually damage the printable surfaces of the sheet. page 23 ACRYLITE digital print pop touch Extruded Sheet Line Bending Test It can be line bent quickly and easily using traditional line bending equipment. The sheet can be heated on the nonprinted side with acceptable results. Line bends will have a slightly lighter appearance compared to the rest of the sheet but this will only be visible under very close scrutiny. Please consult with your printer manufacturer to determine if the ink is formable. Thermoforming Thermoforming to moderate draw ratios is possible. However as the draw ratio increases the printable surface becomes correspondingly thinner. This may compromise the final printed product. It is recommended that a few test samples be made first to evaluate the appearance of the part. Please consult with your printer manufacturer to determine if the ink is formable. Buffing Buffing can change edge appearance from a matte to glossy look. For the best edge finish result perform an initial wet sanding operation. This will remove any saw cut marks. The same buffing equipment can be used on the edge of the digital print sheet as used with other acrylic sheet.

Precautions should be taken to protect this material from flames and high heat sources. ACRYLITE sheet usually burns rapidly to completion if not extinguished. The products of combustion if sufficient air is present are carbon dioxide and water. However in many fires sufficient air will not be available and toxic carbon monoxide will be formed as it will when other common combustible materials are burned. We urge good judgement in the use of this versatile material and recommend that building codes be followed carefully to assure it is used properly. Compatibility Like other plastic materials ACRYLITE sheet is subject to crazing cracking or discoloration if brought into contact with incompatible materials. These materials may include cleaners polishes adhesives sealants gasketing or packaging materials cutting emulsions etc. See the Tech Briefs in this series for more information or contact your ACRYLITE sheet Distributor for information on a specific product.
