How to Spot a Preprint Autograph: 5 Warning Signs

Over the years, I’ve seen a flood of so-called autographs online that are actually pre-printed signatures. They’re easy and inexpensive to reproduce in mass quantities, and they can fool buyers who don't know what to look for.

If you're buying celebrity autographs, knowing how to recognize a preprint is an important part of collecting.

What Is a Preprint Autograph?

Simply put, a preprint autograph is a photographic or printed reproduction of a signature, rather than an autograph actually signed by the person.

Someone may take an original signed photograph, scan or photograph it, and produce copies of the image. The resulting copies can look remarkably similar to the original, but the signature is part of the printed image rather than actual ink or paint applied to the item.

Some celebrities have also used pre-printed photographs for fan mail because they cannot personally sign every autograph request they receive. Regardless of how the original signature was created, a preprint is not a hand-signed autograph.

Some sellers clearly identify preprints with terms such as “PP,” “RP,” “reprint,” or “facsimile.” Unfortunately, other listings may use confusing wording or bury the fact that the signature is printed.

The key distinction is simple: a genuine autograph is actually signed by the person. A preprint is an image of a signature.

How to Spot a Pre-Printed Autograph

Unfortunately, it isn't always possible to determine whether an autograph is genuine simply by looking at a listing photograph. However, if you have the item in hand, there are several things you can look for.

1. Look for a Flat, Printed Appearance
A preprinted signature is part of the photograph or printed image itself. Under close examination, it may have the same flat appearance and surface characteristics as the surrounding photograph.

A genuine signature, by comparison, is applied to the surface of the item with ink, paint, or another writing medium.

This isn't always easy to see with the naked eye, particularly in online photographs, so don't rely on this test alone.

2. Use the Reflection Test
Hold the photograph under a bright light and carefully change the angle.

With a genuine autograph, the ink or paint may reflect light differently from the photographic surface surrounding it. A printed signature, however, is part of the photograph and generally reflects light in the same manner as the surrounding printed image.

This can be a useful clue, although the results can vary depending on the type of photograph, printing process, and writing instrument.

3. Compare Identical Copies
This can be one of the most useful ways to spot a preprint.

If you find multiple copies of what appears to be the same signed photograph, compare the signatures carefully. Genuine hand-signed autographs naturally vary from one signing to another.

If the signature is positioned and shaped exactly the same way on multiple copies, that's a strong indication that you're looking at a reproduction.

You can also search online for the photograph and see whether the exact same signature appears on multiple copies of the image.

4. Examine the Signature Carefully
A genuine autograph is physically applied to the item, while a printed signature is part of the image.

Depending on the ink and surface, a genuine signature may have subtle differences in texture, coverage, or appearance compared with the photograph underneath it.

Be careful when handling collectible photographs. Do not rub, scrape, or otherwise attempt to alter the signature to determine whether it is real.

When possible, comparing the item with a known authentic autograph signed with a similar type of pen can also be helpful.

5. Examine the Signature Under Magnification
Magnification can sometimes reveal details that aren't obvious to the naked eye.

A printed signature may show characteristics of the printing process, such as dots or other patterns that are consistent with the rest of the photograph. 

A genuine signature may instead show the characteristics of ink or paint applied directly to the surface. A magnifying glass or suitable digital magnification can therefore provide another useful clue. However, printing technologies vary, and magnification alone cannot always establish authenticity.

How to Spot Preprints When Shopping Online

The biggest problem with preprints is that you often can't examine the item in person before purchasing it.

When searching for autographs on eBay or elsewhere, pay close attention to the seller's description. Look for terms such as:

PP, RP, preprint, reprint, facsimile, printed signature, reproduction, autopen, or secretarial.

On eBay, you can also use negative keywords when searching for autographs. For example:

johnny depp signed photo -rp -pp -reprint -preprint -print -rpnt -copy

These searches can help eliminate many listings that contain those terms.

However, be careful about searching the description as well as the title. A legitimate seller may mention terms such as “not a preprint” or “we do not sell reprints.” You don't want to eliminate legitimate listings simply because the seller used the word in the description.

Why Do Preprint Autographs Exist?

Many celebrities receive far more autograph requests than they could possibly fulfill personally.

For that reason, some celebrities and fan-mail services have used pre-printed photographs or other reproduction methods to respond to fans.

There's nothing inherently wrong with a preprint when it is clearly represented as a preprint. The problem occurs when a printed signature is presented to a buyer as though it were an authentic hand-signed autograph.

For collectors, that distinction is extremely important.

Preprints, Secretarial Signatures, and Autopens Are Different

It's also important to understand that not every non-authentic signature is technically a preprint.

• Preprint: A photograph or image of a signature that has been reproduced as part of the item.
• Secretarial signature: Someone other than the celebrity signs the item on the celebrity's behalf.
• Autopen: A machine reproduces a signature using a mechanical or automated process.
• Facsimile: A reproduction intended to imitate an original signature.
• Authentic autograph: The person personally signs the item by hand.

These distinctions matter because they are produced in very different ways, even though none of the first four represents a genuine hand-signed autograph from the celebrity.

Why Authenticity Matters

In today's market, buyers can encounter questionable autographs from many different sources, sometimes accompanied by certificates that may look impressive but provide little meaningful assurance.

That's why provenance, sourcing, authentication, and the reputation of the seller all matter when purchasing autographs.

Bottom Line

Learning how to recognize a preprint autograph can help you avoid paying for a printed reproduction when you're looking for a genuine hand-signed collectible.

Look closely at the signature, compare duplicate photographs when possible, examine the item under magnification, and pay attention to the seller's description. Most importantly, consider who you're buying from and how the autograph was obtained.

A certificate alone shouldn't be the only reason you trust an autograph. The source, provenance, authentication, and reputation of the seller all matter.

If you're looking for genuine celebrity autographs, take the time to educate yourself and buy from a seller you can trust.

Because in the autograph business, authenticity isn't just important. It's everything.
