RAL is actually a colour matching system found in Europe that is created and administrated by the German RAL gGmbH (RAL non-profit LLC), that is a subsidiary of the German RAL Institute. In colloquial speech RAL refers to the RAL Classic system, mainly employed for varnish and powder coating but nowadays you can find reference panels for plastics too. Approved RAL products are furnished with a hologram as of early 2013 to make unauthorised versions hard to produce. Imitations may show different hue and colour when observed under various light sources.
RAL Colour Charts are perfect for use in reference to choose an appropriate colour for painting using powder coat colours although other tools including RAL Colour Swabs and RAL Colour Control Cards are often more useful.
A RAL Colour Chart is ideal for hanging on the wall for general reference as well as for use when discussing power coating colours over the phone. However, they are not perfect for utilization in the workshop, especially if they are pinned towards the wall. This is when RAL Colour Swabs and Control Cards are available in.
A RAL Shade Swab is keen on colour coated plastic with each fan detailing a different RAL Tone & Colour. This fan is great for utilization in the task shop in addition to off site as well as at a customers factory when discussing important powder coating decisions. The RAL Shade Swab can be placed on an item to provide a much more accurate representation of the intended finished powder coating to me applied to the metal component. Most Swabs have several hundred colours to them offering an entire selection of colours, shades and tones available as powder coated finishes, and the RAL Swab will help to determine the preffered selection of powder coated finish.
However, the limitations of the RAL Shade & Colour Swabs are nearly as tight as the ones from the RAL Tone Charts pinned towards the office wall. The little Swab tabs that are generally only 100mm long and 40mm wide tend not to present an exact colour match, only a close representation. This is where a RAL Colour Control Card is necessary.
The Colour Control Card is really a large specially prepared colour coated card prepared from the paint manufacturer. powder coating Colour Cards offer a ideal match from the manufacturers paint and will be kept as reference for later colour matching exercises. RAL Coating Cards are compatible with permanent colour references for technical documentation as well as legal contract referencing. Whilst all colours might vary slightly because of changing powder coating environments and respective nacmlk regimes, the Ral Shade Card is the definitive reference for paint matching against RAL Powder Coating Colours.
Ral Colour Swabs are available in the K7 format which shows 5 colours per fan finger, and therefore is really a cheaper fan type and also the K5 which includes more fan fingers each of which is dedicated to one particular RAL tone, shade or colour. Ral Colour Charts are accessible for purchase within the C&S Processing website at great rates.
In 1927 the German Reichs-Ausschuß für Lieferbedingungen und Gütesicherung (Imperial Commission for Delivery Terms and Quality Assurance) invented a selection of forty colours under the name of “RAL 840”. Prior to that date manufacturers and customers had to exchange samples to illustrate a tint, whereas from then on they might rely on numbers.
Inside the 1930s the numbers were changed uniformly to four digits and also the collection was renamed to “RAL 840 R” (R for revised). With tints constantly included in the collection, it had been revised again in 1961 and changed to “RAL 840-HR”, which consists of 210 colours and is also being used to this day. Inside the 1960s the colours were given supplemental names to prevent confusion in case of transposed digits.
As “RAL 840-HR” covered only matte paint the 1980s saw the invention of “RAL 841-GL” for glossy surfaces, restricted to 193 colours. A main criterion for colours inside the RAL Classic collection will be of “paramount interest”. Therefore, most of the colours in it are utilized on warning and traffic signs or are dedicated to government departments and public services (as an example: RAL 1004 – Swiss Postal Service, RAL 1021 – Austrian Postal Service, RAL 1032 – German Postal Service).
