Profile: Leneta Co., Inc. offers test charts, equipment for the paint and coat industry. We deal with sealed charts & cards, unsealed charts, special substrates, printing ink & paper, scrub resistance, sag & leveling, metal panels & application equipment. Our opacity chart is a combination of black and white areas, large enough for wide aperture reflectance instruments, as well as for visual opacity and color observations. Our release charts have a unique surface which is readily wetted by waterborne or solventborne paints, but from which the dried film can be stripped with adhesive tape. Our printing ink drawdown sheets are available in nine different grades of paper & these sheets provide substrates for testing ink qualities.
