How to frame a sonogram so it does not fade

Almost everyone asks us to frame the original sonogram. We tell them not to. That little printout is thermal paper, the same stuff as a gas station receipt. It is already fading, and a frame will not stop it.

We have been cutting frames and mats in a New Jersey workshop since 2014. Sonogram orders come in every week. This is the thing we wish people knew first.

Your sonogram is a receipt

Thermal paper has no ink in it. The image is a chemical coating that turns dark when the printer heats it. Heat made the picture. Heat also erases it.

Most sonogram printouts go faint in 2 to 7 years. In a hot car or a sunny window, one summer can do it. We have had customers open a keepsake box after 10 years and find a blank gray sheet. Nothing left to frame.

Scan it today

Do not wait for the weekend. Scan the sonogram at 600 dpi or higher. A flatbed scanner is best. Save it as a TIFF or a high quality JPG, then back it up somewhere that is not your phone.

No scanner? Your phone will do. Lay the print flat on white paper near a window. Skip the flash. Hold the phone straight above it, not off to one side. Wipe your lens first, because a smudge softens the fine detail.

Some hospitals still have the digital file. Ask the imaging desk. They can often burn a disc or email a copy. It beats any scan you can make at home.

Print the copy on real photo paper

Now print the scan on photo paper. Any photo lab will do it for a few dollars. Ask for a matte or luster finish. Glossy shows every fingerprint under glass.

Print it at the same size as the original, or a little bigger. Blowing a 3 x 4 scan up to 8 x 10 shows every speck of paper grain. About 150 percent is the limit we would push.

A photo print, behind glass and out of direct sun, holds its image for decades. The thermal original cannot do that. So frame the copy. Put the original in a drawer.

Never laminate it, and keep the tape away

Please do not laminate a sonogram. We say this a lot and people still do it.

Thermal paper starts to darken around 190 F. A pouch laminator runs at 250 to 300 F. You will pull out a black rectangle. Cold laminate is no better, because the adhesive eats the coating over the next few months.

The coating reacts to more than heat. Tape, glue dots, rubber cement, and sticky album pages will bleach a white blotch right where they touch. Hand lotion and hand sanitizer do it too.

Soft PVC is the other problem. Clear vinyl sleeves and magnetic albums lift the image right off the paper. Store the original flat in a plain paper envelope. A dark drawer at room temperature is fine.

The size problem, and the mat that fixes it

Sonogram prints are small and odd. Most run about 4 x 3 inches. Some come off the machine as a strip about 3.5 inches wide and 9 inches long. Almost none of them match a store frame.

People cram a 3 x 4 print into a 4 x 6 frame. It looks like a leftover. Give it room instead. A 3 x 4 opening in an 8 x 10 frame leaves 2.5 inches of mat on each side.

We cut the opening about 1/4 inch smaller than the print. The mat then laps 1/8 inch over each edge and holds it in place. No tape touches the print.

We cut every mat to order in our shop, so an odd opening costs nothing extra. Send us the exact print size and we cut for it. Our sonogram frames are built that way, with solid pine moulding and an opening sized to your print.

What UV acrylic does and does not do

UV acrylic blocks about 98 percent of UV light. That is real help for a photo print. It will not save thermal paper.

UV filtering does nothing about heat, and heat is what kills the coating. It does nothing about the slow chemical fade that happens in the dark either. We still put UV acrylic on sonogram frames. The photo copy behind it will hold its color much longer.

Where to hang it

Pick an inside wall. Skip the spot over the fireplace and the wall that gets afternoon sun. Bathrooms are rough too, since steam swells paper and mats.

Hanging over a radiator is the worst one we see. Warm air rising past the back of a frame will cook a thermal print. A photo copy shrugs it off.

A nursery wall away from the window is about perfect. Room temperature and no direct sun. That is the whole ask.

The shadow box option

A shadow box gives you depth. We build ours 1 to 2 inches deep inside. That is enough for the photo copy plus a small object or two.

The hospital bracelet is the usual pick, and the little knit hat works too. First shoes need about 2 inches of depth, so tell us before we build. Mount objects with cotton thread or clear strips, not glue, so they can come out later.

Questions we hear a lot

Can I frame the original if I am careful?

You can. We would rather you did not. If the original is all you have, scan it first, then frame it with UV acrylic. Hang it away from sun and heat, and expect it to fade anyway. That is the paper, not the frame.

My sonogram already looks faint. Is it too late?

Maybe not. Scan it now at the highest setting your scanner has. A faint image can often be pulled back with a contrast bump in any photo app. Once it goes fully blank, though, there is nothing to recover.

What size frame should I order?

Measure the print edge to edge with a ruler. Send us that number, not the size you think it is. For a single 3 x 4 print we like an 8 x 10 frame with a mat. For a long strip, a 9 x 12 frame with a tall opening beats trimming the strip down.
