減少注塑工藝調(diào)整時(shí)的影響
非色差原因需調(diào)整注塑工藝參數(shù)時(shí)，盡可能不改變注塑溫度、背壓、注塑周期及色母加入量，調(diào)整同時(shí)還需觀察工藝參數(shù)改變對(duì)色澤的影響，如發(fā)現(xiàn)色差應(yīng)及時(shí)調(diào)整。盡可能避免使用高注射速度、高背壓等引起強(qiáng)剪切作用的注塑工藝，防止因局部過熱或熱分解等因素造成的色差。嚴(yán)格控制料筒各加熱段溫度，特別是噴嘴和緊靠噴嘴的加熱部分。
掌握料筒溫度、色母量對(duì)產(chǎn)品顏色變化的影響
在進(jìn)行色差調(diào)整前還必須知道產(chǎn)品顏色隨溫度、色母量變化的趨勢(shì)。不同色母隨生產(chǎn)的溫度或色母量的改變，其產(chǎn)品顏色變化規(guī)律是不同的。可通過試色過程來確定其變化規(guī)律。除非已知道這種色母顏色的變化規(guī)律，否則不可能很快地調(diào)好色差，尤其是在采用新色母生產(chǎn)的調(diào)色時(shí)。
