Transparent yellow base ink with high transparency and preparation process

The invention provides high-transparency transparent yellow base ink and a preparation process thereof, and the high-transparency transparent yellow base ink is prepared from the following production raw materials in parts by weight: 30-80 parts of a filter cake, 20-60 parts of varnish, 4-20 parts of mixed oil, 0.2-0.5 part of a demulsifier, 0.3-0.7 part of nanoscale TiO2-WO3 composite powder and 0.3-0.6 part of an active additive. The demulsifying agent is beneficial to improving the kneading effluent rate in the kneading effluent treatment step of the preparation process, so that the water content is reduced, and the working efficiency is improved; the nanoscale TiO2-WO3 composite powder is combined with an oscillation dehydration treatment step of a preparation process, so that dehydration is facilitated, and the water content is further reduced; meanwhile, the nano-scale TiO2-WO3 composite powder is uniformly dispersed in the printing ink, so that the wear resistance is favorably improved; the active addi
