I have been using Spectro printing ink for a while now and I must say it is excellent. The ink quality is top-notch, producing clear and vibrant prints. The ink dries quickly without smudging, which is great. The customer service provided by Spectro is also excellent. They are always helpful and responsive. Overall, I am very satisfied with Spectro printing ink and highly recommend it.
