A medical device may require a readable marking to help the user understand, recognize, or manipulate the product. Numbers, symbols, labeling, and instructions are all examples of marking, and each has a function. Because this information is often applied to small and/or irregularly shaped surfaces, the printing technique should be selected appropriately.
Regarding medical device printing for manufacturers, the aim is to create markings that are both clear and suitable for a particular product. The material, surface shape, size of the graphics, durability, and purpose should all be considered before the production process begins.
Why Do Medical Devices Need Clear Markings?
Medical product markings are not always intended for decoration. Such markings may assist users in identifying control mechanisms, component parts, and instructional information.
Examples of such include:
- Measurement scales
- Product identification
- Control markings
- Directional markings
- Safety markings
- References
- Instructions
- Brand name
The effectiveness of a medical product is greatly reduced by a poorly readable marking. This is why it is essential from the outset.
What Makes Medical Components Difficult to Print?
Medical parts vary greatly in their geometry and materials used. Some parts are made up of flat, smooth surfaces, whereas others may have curved or recessed areas, or very small areas.
There are a number of reasons why the procedure can be difficult:
- Little surface area
- Curvature or irregular shapes
- Small fonts
- Complex symbols
- Variety of material
- Coating
- High material consistency
The printing procedure must be compatible with these characteristics. Conducting tests on the real part helps identify whether the chosen procedure will meet the expectations.
How Does Material Choice Affect the Printing Process?
The layer beneath the graphic can affect the adhesion, appearance, and lifespan of the ink. These properties can be different for plastics, metals, coatings, and other treated materials.
Before manufacturing, the manufacturer needs to consider:
- surface texture
- material
- flexibility
- coating
- cleaning agent exposure
- temperature
- handling
Even a smooth surface may require additional treatment before printing. Cleaning and testing will provide a better foundation for the final graphic product.
Where Can Branding Fit Into Medical Products?
Branding will assist manufacturers in creating consistency among their products and their components. The use of a logo will aid users in identifying either the company or product line.
Company logo printing services will be useful where businesses require a company logo or brand graphics to be printed on appropriate medical components.
A logo can be seen on:
- Device housings
- Control panels
- Handles
- Covers of equipment
- Packaging components
- Accessories
Proper sizing and positioning should be considered. A logo must be visible but must not interfere with essential operating information.
Why Does Design Matter?
Good printing starts with good artwork. Sometimes a complex design may be hard to print because it needs to be reduced in size to fit the small medical part.
The following should be checked before the printing process begins:
- Logo proportions
- Font size
- Thickness of lines
- Spacing of graphics
- Printing size
- Colors needed
- Positioning
Simple designs with clear lines make the printing process easy. It is also important to ensure the design is accurate by creating a sample.
How Can Curved Surfaces Be Handled?
Some medical devices have rounded and indented areas where conventional printing may not suit them. Flexible printing can allow different approaches to accommodate that.
The component’s shape needs to be checked prior to the manufacturing process. Various factors, such as curvature, depth, available space, and graphic placement, will influence the outcome.
A sample can assist in verifying the following:
- Graphic positioning
- Amount of printed area
- Legibility
- Alignment
- Surface suitability
Checking the real shape of the part is especially valuable for components with unconventional designs.
What Role Does Print Durability Play?
Medical components can either be subjected to frequent handling or to cleaning procedures. A mark which looks good initially may not be appropriate if it is no longer legible after continued usage.
The factors which affect durability can include:
- Frequent handling
- Cleaning procedures
- Chemicals
- Temperature
- Material surface
- Life span of the product
All the above factors need to be considered before choosing the print method, so that the chosen print procedure matches the product’s environment.
How Does Production Volume Affect Quality?
Sometimes a small order and a big batch might need to be approached differently. High-volume production places greater importance on repeatability and process control.
Checking during high-volume production might include:
- Part placement
- Consistency of ink
- Machine parameters
- Graphic registration
- Drying or curing
- Print quality
- Part quality
This will help catch any problems before they affect a big batch. Consistent parameters will also make future production easier to repeat.
Can Custom Branding Be Used Beyond Standard Logos?
A business does not have to go for the basic company logo all the time. There are some cases that may require branding, product information, and uniqueness.
Custom logo printing helps businesses apply customized artwork to products or parts of products.
Some of the things that may be included here include:
- Logo sizes
- Graphics for specific products
- Different colors
- Symbols
- Customized texts
- Identification
All of these should still be done keeping in mind that the available surface is used for specific purposes. Having too much information in a limited space makes the markings hard to read.
What Can Help Prevent Common Printing Problems?
Many problems can be solved even before the first production run. Spending time on testing the material, the artwork, and its positioning is always worth the effort.
A straightforward preparation procedure may consist of the following points:
- Checking the final artwork
- Testing the real material
- Verifying graphic positioning
- Color and contrast verification
- Examining a sample
- Verifying durability requirements
Finding a Suitable Printing Partner
Precision is needed when printing on medical components because printing marks can be used for identification purposes and general use. The ideal print company should know the significance of consistency in graphics, compatibility, proper preparation, and quality control.
Pad Print USA can assist firms in analyzing their product specifications and finding ways to print medical components and any other product. An early discussion of the print project can help establish an effective process for that particular product.
