Too Long; Didn't Read
In simple terms, it involves finding a photo printing service online to print some photos, and then attaching a printed QSL card with relevant information (after cutting it down) to the back of the photos.
Photo printing
As for printing, there are many different methods. However, I have experienced situations where photos printed using a particular method would fade over time, so I chose to use the photo printing option.
Online, most of the reprints are made using silver halide processes (many are laser-based silver halide prints). Silver halide prints seem to be a better option.
The price varies depending on the specific channel and the materials used by different vendors, such as the type of photo paper, the silver halide printing process, the equipment used, and even the courier service. Some prints cost a few cents per sheet, while others cost several dollars per sheet. I recommend ordering a small batch to test the quality before placing a large order (in theory, if you're ordering in bulk, this method wouldn't be suitable).
It is recommended to print out 5-inch photos, as these are the closest in size to standard QSL cards (and smaller). Additionally, printed photos typically have no borders, which makes them look good.
Important things to note: The materials on the back of different photo papers are different. Fuji and Leica photo paper is not easy to write on or stamp (if it is, you can simply make a QSL stamp and put it on the back). The absorbency will also vary slightly. However, adhesive tape can be used, so you can stand up the photos with ordinary A4 paper.
Back printing
I am GitHub I created a template based on LaTeX that can format QSL cards approximately 5 inches in size. Then, back.tex On the back of a single QSL card, you fill in some relevant information, and then print it (set "original size" when printing). Then, use the back to write down the contact information, and then send it out.
Pros and cons
The advantage is that if you don't want to order in bulk or print easily faded cards at a printing shop, and you also don't want to buy an inkjet printer and related supplies, this method of producing very small batches could be a good option. The price per card is also not expensive (I bought 20 5-inch photos for 10 yuan, including printing and adhesive strips, which were purchased from Bai Piao).
On the downside, there are quite a few drawbacks.
- First, it's complicated to produce; the back of the printed QSL card needs to be cut and glued, and the output may not be as high as that of CWO.
- The finished product will be curved; the photograph itself is already curved, and the adhesive strip also bends.
- The back side is not waterproof and easily gets dirty; (printing may also cause it to get dirty, especially if there are issues with the printer).
- It looks rough, especially the paper stuck to the back – if it's been torn by hand.
