Avoid direct sunlight and artificial light

To protect autographs on plastic, it is important to keep them away from direct sunlight and artificial light. This is because light, especially ultraviolet (UV) light, can cause plastic to degrade.

UVA, UVB, and UVC rays all have different effects on the skin, and similarly, they affect plastic in distinct ways. UVA has the longest wavelengths, ranging from 320-400 nanometers, and can cause tanning. UVB rays, with a range of 280-320 nanometers, are responsible for sunburns. UVC, with the shortest wavelengths of around 100-280 nanometers, is known for its germicidal effects, destroying the DNA of microorganisms.

When it comes to plastic, UV rays can cause changes to the surface layer, and in some cases, lead to the complete failure of the plastic component. Additionally, visible light can also contribute to the degradation of plastic, although to a lesser extent. The combination of light and heat can further accelerate the deterioration process.

To safeguard your autographs on plastic, it is recommended to store them in a dark room that receives minimal natural sunlight. If you wish to display your autographs, use a UV-protective glass case or frame to minimize the harmful effects of sunlight and artificial light. Even a few hours of sunlight a day can cause significant damage, so it is crucial to take the necessary precautions.

By following these steps and keeping your autographs away from direct sunlight and artificial light, you can effectively slow down the fading process and maintain the condition of your valuable collection.

Store in a cool, dry, dark place

Temperature and humidity play a significant role in preserving autographs. Collectors should store their autographs in a cool, dry, and dark place. The ideal temperature is between 65 and 75 degrees Fahrenheit, with a relative humidity between 35 and 55 percent. Avoid storing items in humid places such as attics, garages, or basements. Instead, opt for a closet, shelf, or drawer in the living space of your home, where temperature and humidity levels typically remain within a safe range.

If you are displaying your autographs, it is crucial to use a UV-protective display case or frame to shield them from sunlight and artificial light, which can cause significant deterioration. Even a couple of hours of sunlight a day can cause damage. When framing, use acid-free matting materials and avoid gluing or taping the document to the mat. Instead, use acid-free mounting corners to secure the autograph.

Additionally, be mindful of the materials used in storage solutions. Avoid cheap plastic storage solutions, as they can release toxic chemicals that will cause your autographs to degrade prematurely and reduce their value. Choose archival-grade storage boxes that come with acid-free envelopes and compartments for secure storage. Ensure that the plastic sleeves are sold as "archival" or "archival-safe" and are made of Mylar (polyester), polyethylene (PE), or polypropylene (PP). Cellophane bags or sleeves are also safe but more expensive options.

Avoid adhesives, sprays, and varnishes

While you may be tempted to use adhesives, sprays, or varnishes to protect your autograph, it is strongly advised against. These products can negatively affect the value of your autograph and cause more harm than good. For example, Mod Podge, a popular adhesive, is essentially just clear-drying Elmer's glue and will inevitably peel off, damaging the signature in the process.

Spray-on sealants and lacquers often contain alcohol, which destroys Sharpie, especially on plastic. Additionally, using shellac or other varnishes will preserve the autograph but will also significantly detract from its value over time.

If you are looking to protect autographs on clothing, avoid using clear fabric paint as it can ruin the integrity of the fabric. Instead, set your iron to the cotton setting with no steam and press it onto the inked area. Then, place the garment in the tumble dryer on a hot setting for around 15 minutes.

When storing your autographs, avoid using plastic storage sleeves or photo boxes that are not labelled as "archival" or "archival safe". These products can release toxic chemicals that will cause your photos to degrade prematurely, altering their appearance and reducing their value. Instead, opt for PVC-free plastic sheets made of Mylar (polyester), polyethylene (PE), or polypropylene (PP).

In summary, while adhesives, sprays, and varnishes may seem like a good idea to protect your autographs, they can often do more harm than good. It is best to avoid these products and opt for alternative methods such as UV-protective cases, acid-free storage materials, and ironing for clothing autographs.

Use UV-protective glass or a display case

If you want to display your autograph collection, it is important to invest in a UV-protective display case. This will ensure that your autographs are protected from the harmful effects of sunlight and artificial light, which can cause significant deterioration. Even a couple of hours of sunlight a day can cause discolouration and fading, so it is important to take the necessary precautions.

UV-protective glass or a display case with UV-filtering laminated glass will act as a barrier, preventing direct exposure to light and slowing down any potential fading. This is especially important if your autographs are displayed in a room that receives natural sunlight. The UV-protective glass will also protect your autographs from artificial light, which can be just as damaging as sunlight.

If you are unable to find a UV-protective display case, you can also use UV-protective spray on your autographs. This will provide an extra layer of protection and help to slow down any potential fading. It is also recommended to store your autographs in a cool, dry, and dark place when they are not on display. A closet, shelf, or drawer located in the living space of your home is ideal, as temperature and humidity levels typically remain within a safe range.

It is worth noting that some sources suggest that any type of glass or display case can act as a magnifying glass, intensifying the effects of sunlight and artificial light. Therefore, it is crucial to only use UV-protective options to ensure the safety of your autographs. Additionally, avoid the use of any adhesives, sprays, or varnishes on your autographs, as these can negatively affect the value and integrity of the signature.

By following these steps and investing in UV-protective glass or a display case, you can effectively protect your autograph collection from the damaging effects of light and ensure their longevity.

Choose PVC-free plastic sheets

When it comes to preserving autographs, it is important to consider the type of material you are protecting. For autographs on plastic, there are specific steps you can take to ensure their longevity. One crucial consideration is to choose PVC-free plastic sheets for protection and display. Here's why:

PVC, or polyvinyl chloride, is a commonly used synthetic polymer. While it has various applications, its impact on health and the environment is a cause for concern. PVC is known to release toxic chemicals during its lifecycle, including dioxins, which are highly toxic and persistent in the environment. Due to these harmful properties, it is advisable to avoid using PVC-based products when preserving autographs.

PVC-free plastic sheets offer a safer alternative. These sheets are made from alternative materials, such as polyethylene terephthalate (PET) or polypropylene (PP), which do not possess the same toxic characteristics as PVC. By opting for PVC-free options, you can protect both the value and condition of your autographs while also minimizing potential health and environmental risks.

When selecting PVC-free plastic sheets, look for options that are specifically designed for archival or preservation purposes. These sheets should be acid-free and of archival quality to ensure they do not react with the ink or damage the autograph over time. Additionally, choose sheets with UV protection to safeguard against the harmful effects of sunlight, as regular glass can accelerate deterioration by acting as a magnifying glass for light.

To further enhance the protection of your autographs, consider using PVC-free plastic sheets in conjunction with other conservation methods. For example, store your autographs in a dark room, away from direct sunlight, or use UV-protective display cases. By combining these methods, you can effectively preserve your autographs for the long term.

By choosing PVC-free plastic sheets, you can confidently display and protect your autographs while maintaining their value and integrity. Remember to also follow other best practices, such as keeping autographs away from moisture and heat sources, to ensure their preservation for years to come.
