Most Common Types of Seals Used in Diploma and Certificate Printing

1. Embossed Seal

An embossed seal is created by pressing a die into the paper, leaving a raised or recessed impression. It’s a traditional and highly respected choice for diplomas.

Pros:

• Elegant and professional look

• Harder to duplicate, adds security

• No ink or foil needed

Cons:

• May be faint on scanned or photocopied versions

• Requires special embossing tools

• Works best only on thicker paper

2. Foil Seal (Gold, Silver, Bronze)

A shiny foil seal is applied using heat or adhesive. Often seen in university diplomas and high-end awards.

Pros:

• Eye-catching metallic finish

• Widely recognized as a mark of authenticity

• Difficult to copy with standard printers

Cons:

• Can peel or fade if low quality

• Slightly more expensive

• Light reflection may affect scans

3. Holographic Seal

A modern security option with 3D or color-shifting effects. Frequently used in government-issued and high-value documents.

Pros:

• Very secure and tamper-resistant

• Nearly impossible to forge

• Gives a modern, premium look

Cons:

• Expensive to produce

• May feel too “commercial” for some certificates

4. Printed/Ink Seal

The simplest option—just printing the seal design directly on the document.

Melted wax is stamped with a seal for a vintage, ceremonial effect.

Pros:

Cons:

• Not practical for large batches

• Doesn’t scan well

6. Digital Seal (For e-Certificates)

A modern choice for online diplomas and certificates, often using QR codes, barcodes, or digital watermarks.

Pros:

• Perfect for digital verification

• Cannot be altered without invalidation

• Easy to share electronically
