A plastic print refers to two distinct concepts:
1. Forensic Science: A Fingerprint Impression
In forensic science, a plastic print is a three-dimensional fingerprint impression left behind when a finger presses into a soft, malleable surface. Think of pressing your finger into fresh paint, wax, soap, or tar. The impression captures the unique ridge detail of the finger. This differs from a latent print (invisible) or patent print (visible, like blood or ink on a surface). As stated in this forensic science resource, "Plastic fingerprints are three-dimensional impressions and can be made by pressing your fingers in fresh paint, wax, soap, or tar."
2. Commercial Printing: Printed Plastic Products
In the context of commercial printing, a "plastic print" refers to items printed on plastic substrates. This could encompass a wide range of products, including:
- Business cards: Often printed on rigid or flexible plastic for durability.
- Flyers and postcards: Printed on plastic for a more unique and durable feel.
- Door hangers: Printed on plastic to withstand the elements.
- Membership and ID cards: Commonly printed on durable plastic for longevity and security. PlasticPrint is an example of a company specializing in this area.
- Keyrings: Custom-printed plastic keyrings are a popular promotional item. An example from Kinbyric shows this.
This type of printing often utilizes techniques like digital printing or screen printing onto various plastic materials like PVC or PET. PrintPapa offers examples of this type of printing. Another aspect is the use of plastics in 3D printing, where various plastics are used to create three-dimensional objects. The quality of prints can vary greatly depending on the material and method (Reddit discussion on Resin vs Plastic 3D printing).
